```
    Description copied from interface: BytesMessage
    
    Reads a byte array from the bytes message stream.
    If the length of array value is less than the number of bytes remaining to be read from the stream, the array should be filled. A subsequent call reads the next increment, and so on.
    If the number of bytes remaining in the stream is less than the length of array value, the bytes should be read into the array. The return value of the total number of bytes read will be less than the length of the array, indicating that there are no more bytes left to be read from the stream. The next read of the stream returns -1.
    
    Specified by:

    Parameters:
    
    value - the buffer into which the data is read

```
    Description copied from interface: BytesMessage
    
    Reads a portion of the bytes message stream.
    If the length of array value is less than the number of bytes remaining to be read from the stream, the array should be filled. A subsequent call reads the next increment, and so on.
    If the number of bytes remaining in the stream is less than the length of array value, the bytes should be read into the array. The return value of the total number of bytes read will be less than the length of the array, indicating that there are no more bytes left to be read from the stream. The next read of the stream returns -1.
    If length is negative, or length is greater than the length of the array value, then an IndexOutOfBoundsException is thrown. No bytes will be read from the stream for this exception case.

    Writes an object to the bytes message stream.
    This method works only for the objectified primitive object types (Integer, Double, Long ...), String objects, and byte arrays.
    
    Specified by:
    
    writeObject in interface BytesMessage
    
    Parameters:
    
    value - the object in the Java programming language ("Java object") to be written; it must not be null
    
    Throws:
    
    JMSException - if the JMS provider fails to write the message due to some internal error.
    
    MessageFormatException - if the object is of an invalid type.
    
    MessageNotWriteableException - if the message is in read-only mode.
  - reset
```
public void reset()
           throws JMSException
```
    Description copied from interface: BytesMessage
    
    Puts the message body in read-only mode and repositions the stream of bytes to the beginning.
    
    Specified by:
    
    reset in interface BytesMessage
    
    Throws:
    
    JMSException - if the JMS provider fails to reset the message due to some internal error.
    
    MessageFormatException - if the message has an invalid format.
  - doBeforeReceive
```
public void doBeforeReceive()
                     throws ActiveMQException
```
    Overrides:
    
    doBeforeReceive in class ActiveMQMessage
    
    Throws:
    
    ActiveMQException
  - 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 JMS provider fails to clear the message body due to some internal error.
  - getBodyLength
```
public long getBodyLength()
                   throws JMSException
```
    Description copied from interface: BytesMessage
    
    Gets the number of bytes of the message body when the message is in read-only mode. The value returned can be used to allocate a byte array. The value returned is the entire length of the message body, regardless of where the pointer for reading the message is currently located.
    
    Specified by:
    
    getBodyLength in interface BytesMessage
    
    Returns:
    
    number of bytes in the message
    
    Throws:
    
    JMSException - if the JMS provider fails to read the message due to some internal error.
    
    MessageNotReadableException - if the message is in write-only mode.
  - doBeforeSend
```
public void doBeforeSend()
                  throws Exception
```
    Overrides:
    
    doBeforeSend in class ActiveMQMessage
    
    Throws:
    
    Exception
  - getType
```
public byte getType()
```
    Overrides:
    
    getType in class ActiveMQMessage
  - 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
    
    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
