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.

doBeforeSend

public void doBeforeSend()
                  throws Exception

Overrides:

doBeforeSend in class ActiveMQMessage

Throws:

Exception

doBeforeReceive

public void doBeforeReceive()
                     throws ActiveMQException

Overrides:

doBeforeReceive in class ActiveMQMessage

Throws:

ActiveMQException

hasNoBody

protected boolean hasNoBody()

Description copied from class: ActiveMQMessage

Helper method for ActiveMQMessage.isBodyAssignableTo(Class).

Overrides:

hasNoBody in class ActiveMQMessage

Returns:

true if the message has no body.

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

getBodyInternal

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

Overrides:

getBodyInternal in class ActiveMQMessage
