compare

public boolean compare(javax.jms.Message message1,
                       javax.jms.Message message2)
                throws java.lang.Exception

Compare two messages. This method delegates the comparison to the appropriate method if the messages are of the same type, and not the same instance.

Specified by:

compare in interface MessageComparer

Parameters:

message1 - one message to be tested for equality

message2 - the other message to be tested for equality

Returns:

true if message1 and message2 are equal

Throws:

java.lang.Exception - for any error

compareMessages

public boolean compareMessages(javax.jms.Message message1,
                               javax.jms.Message message2)
                        throws java.lang.Exception

Compare two Message instances. This method does nothing - subclasses needing the functionality must implement it.

Parameters:

message1 - one message to be tested for equality

message2 - the other message to be tested for equality

Returns:

false if invoked

Throws:

java.lang.Exception - for any error

compareBytesMessages

public boolean compareBytesMessages(javax.jms.BytesMessage message1,
                                    javax.jms.BytesMessage message2)
                             throws java.lang.Exception

Compare two BytesMessage instances. This method does nothing - subclasses needing the functionality must implement it.

Parameters:

message1 - one message to be tested for equality

message2 - the other message to be tested for equality

Returns:

false if invoked

Throws:

java.lang.Exception - for any error

compareMapMessages

public boolean compareMapMessages(javax.jms.MapMessage message1,
                                  javax.jms.MapMessage message2)
                           throws java.lang.Exception

Compare two MapMessage instances. This method does nothing - subclasses needing the functionality must implement it.

Parameters:

false if invoked

Throws:

java.lang.Exception - for any error

compareObjectMessages

public boolean compareObjectMessages(javax.jms.ObjectMessage message1,

                              throws java.lang.Exception

                              throws java.lang.Exception

Compare two StreamMessage instances. This method does nothing - subclasses needing the functionality must implement it.
