getJMSMessageID

public String getJMSMessageID()

Description copied from interface: Message

Gets the message ID.

The JMSMessageID header field contains a value that uniquely identifies each message sent by a provider.

When a message is sent, JMSMessageID can be ignored. When the send or publish method returns, it contains a provider-assigned value.

A JMSMessageID is a String value that should function as a unique key for identifying messages in a historical repository. The exact scope of uniqueness is provider-defined. It should at least cover all messages for a specific installation of a provider, where an installation is some connected set of message routers.

All JMSMessageID values must start with the prefix 'ID:'. Uniqueness of message ID values across different providers is not required.

Since message IDs take some effort to create and increase a message's size, some JMS providers may be able to optimize message overhead if they are given a hint that the message ID is not used by an application. By calling the MessageProducer.setDisableMessageID method, a JMS client enables this potential optimization for all messages sent by that message producer. If the JMS provider accepts this hint, these messages must have the message ID set to null; if the provider ignores the hint, the message ID must be set to its normal unique value.

Specified by:

getJMSMessageID in interface Message

Returns:

the message ID

See Also:

Message.setJMSMessageID(String), MessageProducer.setDisableMessageID(boolean)

setJMSMessageID

public void setJMSMessageID(String jmsMessageID)
                     throws JMSException

Description copied from interface: Message

Sets the message ID.

This method is for use by JMS providers only to set this field when a message is sent. This message cannot be used by clients to configure the message ID. This method is public to allow a JMS provider to set this field when sending a message whose implementation is not its own.

Specified by:

setJMSMessageID in interface Message

Parameters:

jmsMessageID - the ID of the message

Throws:

JMSException - if the JMS provider fails to set the message ID due to some internal error.

See Also:

Message.getJMSMessageID()

getJMSTimestamp

public long getJMSTimestamp()
                     throws JMSException

Description copied from interface: Message

Gets the message timestamp.

The JMSTimestamp header field contains the time a message was handed off to a provider to be sent. It is not the time the message was actually transmitted, because the actual send may occur later due to transactions or other client-side queueing of messages.

When a message is sent, JMSTimestamp is ignored. When the send or publish method returns, it contains a time value somewhere in the interval between the call and the return. The value is in the format of a normal millis time value in the Java programming language.

Since timestamps take some effort to create and increase a message's size, some JMS providers may be able to optimize message overhead if they are given a hint that the timestamp is not used by an application. By calling the MessageProducer.setDisableMessageTimestamp method, a JMS client enables this potential optimization for all messages sent by that message producer. If the JMS provider accepts this hint, these messages must have the timestamp set to zero; if the provider ignores the hint, the timestamp must be set to its normal value.

Specified by:

getJMSTimestamp in interface Message

Returns:

the message timestamp

Throws:

JMSException - if the JMS provider fails to get the timestamp due to some internal error.

See Also:

Message.setJMSTimestamp(long), MessageProducer.setDisableMessageTimestamp(boolean)

setJMSTimestamp

public void setJMSTimestamp(long timestamp)
                     throws JMSException

Description copied from interface: Message

Sets the message timestamp.

This method is for use by JMS providers only to set this field when a message is sent. This message cannot be used by clients to configure the message timestamp. This method is public to allow a JMS provider to set this field when sending a message whose implementation is not its own.

Specified by:

setJMSTimestamp in interface Message

Parameters:

timestamp - the timestamp for this message

Throws:

JMSException - if the JMS provider fails to set the timestamp due to some internal error.

Message.getJMSTimestamp()

getJMSCorrelationIDAsBytes

public byte[] getJMSCorrelationIDAsBytes()
                                  throws JMSException

Description copied from interface: Message

Gets the correlation ID as an array of bytes for the message.

The use of a byte[] value for JMSCorrelationID is non-portable.

Specified by:

getJMSCorrelationIDAsBytes in interface Message

Returns:

the correlation ID of a message as an array of bytes

Throws:

JMSException - if the JMS provider fails to get the correlation ID due to some internal error.

See Also:

Message.setJMSCorrelationID(String), Message.getJMSCorrelationID(), Message.setJMSCorrelationIDAsBytes(byte[])

setJMSCorrelationIDAsBytes

public void setJMSCorrelationIDAsBytes(byte[] correlationID)
                                throws JMSException

Description copied from interface: Message

Sets the correlation ID as an array of bytes for the message.

The array is copied before the method returns, so future modifications to the array will not alter this message header.

If a provider supports the native concept of correlation ID, a JMS client may need to assign specific JMSCorrelationID values to match those expected by native messaging clients. JMS providers without native correlation ID values are not required to support this method and its corresponding get method; their implementation may throw a java.lang.UnsupportedOperationException.

The use of a byte[] value for JMSCorrelationID is non-portable.

Specified by:

setJMSCorrelationIDAsBytes in interface Message

Parameters:

correlationID - the correlation ID value as an array of bytes

Throws:

JMSException - if the JMS provider fails to set the correlation ID due to some internal error.

See Also:

Message.setJMSCorrelationID(String), Message.getJMSCorrelationID(), Message.getJMSCorrelationIDAsBytes()

setJMSCorrelationID

public void setJMSCorrelationID(String correlationID)
                         throws JMSException

Description copied from interface: Message

Sets the correlation ID for the message.

A client can use the JMSCorrelationID header field to link one message with another. A typical use is to link a response message with its request message.

JMSCorrelationID can hold one of the following:

• A provider-specific message ID
• An application-specific String
• A provider-native byte[] value

Since each message sent by a JMS provider is assigned a message ID value, it is convenient to link messages via message ID. All message ID values must start with the 'ID:' prefix.

In some cases, an application (made up of several clients) needs to use an application-specific value for linking messages. For instance, an application may use JMSCorrelationID to hold a value referencing some external information. Application-specified values must not start with the 'ID:' prefix; this is reserved for provider-generated message ID values.

If a provider supports the native concept of correlation ID, a JMS client may need to assign specific JMSCorrelationID values to match those expected by clients that do not use the JMS API. A byte[] value is used for this purpose. JMS providers without native correlation ID values are not required to support byte[] values. The use of a byte[] value for JMSCorrelationID is non-portable.

Specified by:

setJMSCorrelationID in interface Message

Parameters:

correlationID - the message ID of a message being referred to

Throws:

JMSException - if the JMS provider fails to set the correlation ID due to some internal error.

getJMSCorrelationID

public String getJMSCorrelationID()
                           throws JMSException

Description copied from interface: Message

Gets the correlation ID for the message.

This method is used to return correlation ID values that are either provider-specific message IDs or application-specific String values.

Specified by:

getJMSCorrelationID in interface Message

Returns:

the correlation ID of a message as a String

Throws:

JMSException - if the JMS provider fails to get the correlation ID due to some internal error.

getJMSReplyTo

public Destination getJMSReplyTo()
                          throws JMSException

Description copied from interface: Message

Gets the Destination object to which a reply to this message should be sent.

Specified by:

getJMSReplyTo in interface Message

Returns:

Destination to which to send a response to this message

Throws:

JMSException - if the JMS provider fails to get the JMSReplyTo destination due to some internal error.

See Also:

Message.setJMSReplyTo(Destination)

setJMSReplyTo

public void setJMSReplyTo(Destination dest)
                   throws JMSException

Description copied from interface: Message

Sets the Destination object to which a reply to this message should be sent.

The JMSReplyTo header field contains the destination where a reply to the current message should be sent. If it is null, no reply is expected. The destination may be either a Queue object or a Topic object.

Messages sent with a null JMSReplyTo value may be a notification of some event, or they may just be some data the sender thinks is of interest.

Messages with a JMSReplyTo value typically expect a response. A response is optional; it is up to the client to decide. These messages are called requests. A message sent in response to a request is called a reply.

In some cases a client may wish to match a request it sent earlier with a reply it has just received. The client can use the JMSCorrelationID header field for this purpose.

Specified by:

setJMSReplyTo in interface Message

Parameters:

dest - Destination to which to send a response to this message

Throws:

JMSException - if the JMS provider fails to set the JMSReplyTo destination due to some internal error.

See Also:

Message.getJMSReplyTo()

getJMSDestination

public Destination getJMSDestination()
                              throws JMSException

Description copied from interface: Message

Gets the Destination object for this message.

The JMSDestination header field contains the destination to which the message is being sent.

When a message is sent, this field is ignored. After completion of the send or publish method, the field holds the destination specified by the method.

When a message is received, its JMSDestination value must be equivalent to the value assigned when it was sent.

Specified by:

getJMSDestination in interface Message

Returns:

the destination of this message

Throws:

JMSException - if the JMS provider fails to get the destination due to some internal error.

See Also:

Message.setJMSDestination(Destination)

public boolean getJMSRedelivered()
                          throws JMSException

Description copied from interface: Message

Gets an indication of whether this message is being redelivered.

If a client receives a message with the JMSRedelivered field set, it is likely, but not guaranteed, that this message was delivered earlier but that its receipt was not acknowledged at that time.

This method is for use by JMS providers only to set this field when a message is delivered. This message cannot be used by clients to configure the redelivered status of the message. This method is public to allow a JMS provider to set this field when sending a message whose implementation is not its own.

Specified by:

setJMSRedelivered in interface Message

Parameters:

redelivered - an indication of whether this message is being redelivered

Throws:

JMSException - if the JMS provider fails to set the redelivered state due to some internal error.

See Also:

Message.getJMSRedelivered()

setJMSType

public void setJMSType(String type)
                throws JMSException

Description copied from interface: Message

Sets the message type.

Some JMS providers use a message repository that contains the definitions of messages sent by applications. The JMSType header field may reference a message's definition in the provider's repository.

The JMS API does not define a standard message definition repository, nor does it define a naming policy for the definitions it contains.

Some messaging systems require that a message type definition for each application message be created and that each message specify its type. In order to work with such JMS providers, JMS clients should assign a value to JMSType, whether the application makes use of it or not. This ensures that the field is properly set for those providers that require it.

To ensure portability, JMS clients should use symbolic values for JMSType that can be configured at installation time to the values defined in the current provider's message repository. If string literals are used, they may not be valid type names for some JMS providers.

Specified by:

setJMSType in interface Message

Parameters:

type - the message type

Throws:

JMSException - if the JMS provider fails to set the message type due to some internal error.

See Also:

Message.getJMSType()

getJMSType

public String getJMSType()
                  throws JMSException

Description copied from interface: Message

Gets the message type identifier supplied by the client when the message was sent.

Specified by:

getJMSType in interface Message

Returns:

the message type

Throws:

JMSException - if the JMS provider fails to get the message type due to some internal error.

See Also:

Message.setJMSType(String)

getJMSExpiration

public long getJMSExpiration()
                      throws JMSException

Description copied from interface: Message

Gets the message's expiration time.

When a message is sent, the JMSExpiration header field is left unassigned. After completion of the send or publish method, it holds the expiration time of the message. This is the the difference, measured in milliseconds, between the expiration time and midnight, January 1, 1970 UTC.

If the time-to-live is specified as zero, JMSExpiration is set to zero to indicate that the message does not expire.

When a message's expiration time is reached, a provider should discard it. The JMS API does not define any form of notification of message expiration.

Clients should not receive messages that have expired; however, the JMS API does not guarantee that this will not happen.

Specified by:

getJMSExpiration in interface Message

Returns:

the message's expiration time value

Throws:

JMSException - if the JMS provider fails to get the message expiration due to some internal error.

See Also:

Message.setJMSExpiration(long)

setJMSExpiration

public void setJMSExpiration(long expiration)
                      throws JMSException

Description copied from interface: Message

Sets the message's expiration value.

This method is for use by JMS providers only to set this field when a message is sent. This message cannot be used by clients to configure the expiration time of the message. This method is public to allow a JMS provider to set this field when sending a message whose implementation is not its own.

Specified by:

setJMSExpiration in interface Message

Parameters:

expiration - the message's expiration time

Throws:

JMSException - if the JMS provider fails to set the message expiration due to some internal error.

See Also:

Message.getJMSExpiration()

getJMSPriority

public int getJMSPriority()
                   throws JMSException

Description copied from interface: Message

Gets the message priority level.

The JMS API defines ten levels of priority value, with 0 as the lowest priority and 9 as the highest. In addition, clients should consider priorities 0-4 as gradations of normal priority and priorities 5-9 as gradations of expedited priority.

The JMS API does not require that a provider strictly implement priority ordering of messages; however, it should do its best to deliver expedited messages ahead of normal messages.

Specified by:

getJMSPriority in interface Message

Returns:

the default message priority

Throws:

JMSException - if the JMS provider fails to get the message priority due to some internal error.

See Also:

Message.setJMSPriority(int)

setJMSPriority

public void setJMSPriority(int priority)
                    throws JMSException

Description copied from interface: Message

Sets the priority level for this message.

This method is for use by JMS providers only to set this field when a message is sent. This message cannot be used by clients to configure the priority level of the message. This method is public to allow a JMS provider to set this field when sending a message whose implementation is not its own.

Specified by:

setJMSPriority in interface Message

Parameters:

priority - the priority of this message

Throws:

JMSException - if the JMS provider fails to set the message priority due to some internal error.

acknowledge

public void acknowledge()
                 throws JMSException

Description copied from interface: Message

Acknowledges all consumed messages of the session of this consumed message.

All consumed JMS messages support the acknowledge method for use when a client has specified that its JMS session's consumed messages are to be explicitly acknowledged. By invoking acknowledge on a consumed message, a client acknowledges all messages consumed by the session that the message was delivered to.

Calls to acknowledge are ignored for both transacted sessions and sessions specified to use implicit acknowledgement modes.

A client may individually acknowledge each message as it is consumed, or it may choose to acknowledge messages as an application-defined group (which is done by calling acknowledge on the last received message of the group, thereby acknowledging all messages consumed by the session.)

Messages that have been received but not acknowledged may be redelivered.

Specified by:

acknowledge in interface Message

Throws:

JMSException - if the JMS provider fails to acknowledge the messages due to some internal error.

IllegalStateException - if this method is called on a closed session.

Session.CLIENT_ACKNOWLEDGE

getJMSDeliveryTime

public long getJMSDeliveryTime()
                        throws JMSException

Description copied from interface: Message

Gets the message's delivery time value.

When a message is sent, the JMSDeliveryTime header field is left unassigned. After completion of the send or publish method, it holds the delivery time of the message. This is the the difference, measured in milliseconds, between the delivery time and midnight, January 1, 1970 UTC.

A message's delivery time is the earliest time when a JMS provider may deliver the message to a consumer. The provider must not deliver messages before the delivery time has been reached.

Specified by:

getJMSDeliveryTime in interface Message

Returns:

the message's delivery time value

Throws:

JMSException - if the JMS provider fails to get the delivery time due to some internal error.

See Also:

Message.setJMSDeliveryTime(long)

setJMSDeliveryTime

public void setJMSDeliveryTime(long deliveryTime)
                        throws JMSException

Description copied from interface: Message

Sets the message's delivery time value.

This method is for use by JMS providers only to set this field when a message is sent. This message cannot be used by clients to configure the delivery time of the message. This method is public to allow a JMS provider to set this field when sending a message whose implementation is not its own.

Specified by:

setJMSDeliveryTime in interface Message

Parameters:

deliveryTime - the message's delivery time value

Throws:

JMSException - if the JMS provider fails to set the delivery time due to some internal error.

See Also:

Message.getJMSDeliveryTime()

getBody

public <T> T getBody(Class<T> c)
              throws JMSException

Description copied from interface: Message

Returns the message body as an object of the specified type. This method may be called on any type of message except for StreamMessage. The message body must be capable of being assigned to the specified type. This means that the specified class or interface must be either the same as, or a superclass or superinterface of, the class of the message body. If the message has no body then any type may be specified and null is returned.

Specified by:

getBody in interface Message

Parameters:

c - The type to which the message body will be assigned.
If the message is a TextMessage then this parameter must be set to String.class or another type to which a String is assignable.
If the message is a ObjectMessage then parameter must must be set to java.io.Serializable.class or another type to which the body is assignable.
If the message is a MapMessage then this parameter must be set to java.util.Map.class (or java.lang.Object.class).
If the message is a BytesMessage then this parameter must be set to byte[].class (or java.lang.Object.class). This method will reset the BytesMessage before and after use.
If the message is a TextMessage, ObjectMessage, MapMessage or BytesMessage and the message has no body, then the above does not apply and this parameter may be set to any type; the returned value will always be null.
If the message is a Message (but not one of its subtypes) then this parameter may be set to any type; the returned value will always be null.

Returns:

the message body

Throws:

MessageFormatException -

• if the message is a StreamMessage
• if the message body cannot be assigned to the specified type
• if the message is an ObjectMessage and object deserialization fails.

JMSException - if the JMS provider fails to get the message body due to some internal error.

                         throws MessageFormatException

Throws:

MessageFormatException

isBodyAssignableTo

public boolean isBodyAssignableTo(Class c)

Description copied from interface: Message

Returns whether the message body is capable of being assigned to the specified type. If this method returns true then a subsequent call to the method getBody on the same message with the same type argument would not throw a MessageFormatException.

If the message is a StreamMessage then false is always returned. If the message is a ObjectMessage and object deserialization fails then false is returned. If the message has no body then any type may be specified and true is returned.

Specified by:

isBodyAssignableTo in interface Message

Parameters:

c - The specified type
If the message is a TextMessage then this method will only return true if this parameter is set to String.class or another type to which a String is assignable.
If the message is a ObjectMessage then this method will only return true if this parameter is set to java.io.Serializable.class or another class to which the body is assignable.
If the message is a MapMessage then this method will only return true if this parameter is set to java.util.Map.class (or java.lang.Object.class).
If the message is a BytesMessage then this this method will only return true if this parameter is set to byte[].class (or java.lang.Object.class).
If the message is a TextMessage, ObjectMessage, MapMessage or BytesMessage and the message has no body, then the above does not apply and this method will return true irrespective of the value of this parameter.
If the message is a Message (but not one of its subtypes) then this method will return true irrespective of the value of this parameter.

Returns:

whether the message body is capable of being assigned to the specified type
