                    throws JMSException

A copy constructor for non-ActiveMQ Artemis JMS TextMessages.

Throws:

JMSException

Method Details

getType

public byte getType()

Overrides:

getType in class ActiveMQMessage

setText

public void setText(String text)
             throws JMSException

Description copied from interface: TextMessage

Sets the string containing this message's data.

Specified by:

setText in interface TextMessage

Parameters:

text - the String containing the message's data

Throws:

JMSException - if the Jakarta Messaging provider fails to set the text due to some internal error.

MessageNotWriteableException - if the message is in read-only mode.

getText

public String getText()

Description copied from interface: TextMessage

Gets the string containing this message's data. The default value is null.

Specified by:

getText in interface TextMessage

Returns:

the String containing the message's data

clearBody

public void clearBody()
               throws JMSException

Description copied from interface: Message

Clears out the message body. Clearing a message's body does not clear its header values or property entries.

If this message body was read-only, calling this method leaves the message body in the same state as an empty body in a newly created message.

Specified by:

clearBody in interface Message

Overrides:

clearBody in class ActiveMQMessage

Throws:

JMSException - if the Jakarta Messaging provider fails to clear the message body due to some internal error.

doBeforeReceive

public void doBeforeReceive()
                     throws ActiveMQException

Overrides:

doBeforeReceive in class ActiveMQMessage

Throws:

ActiveMQException

getBodyInternal

protected <T> T getBodyInternal(Class<T> c)

Overrides:

getBodyInternal in class ActiveMQMessage

isBodyAssignableTo

public boolean isBodyAssignableTo(Class c)

Description copied from class: ActiveMQMessage

From the specs:

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.

Specified by:

isBodyAssignableTo in interface Message

Overrides:

isBodyAssignableTo in class ActiveMQMessage

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
