Method Detail

compareBytesMessages

public boolean compareBytesMessages(javax.jms.BytesMessage message1,
                                    javax.jms.BytesMessage message2)

Compare two BytesMessage instances. It is impossible to tell via the BytesMessage API if the message bodies refer to the same byte array, so this implementation always returns false

Overrides:

compareBytesMessages in class AbstractMessageComparer

Parameters:

message1 - the message to compare

message2 - the message to compare

Returns:

false when invoked

compareMapMessages

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

Compare two MapMessage instances

Overrides:

compareMapMessages in class AbstractMessageComparer

Parameters:

message1 - the message to compare

message2 - the message to compare

Returns:

true if the messages bodies contain references to the same objects

Throws:

java.lang.Exception - for any error

compareObjectMessages

public boolean compareObjectMessages(javax.jms.ObjectMessage message1,
                                     javax.jms.ObjectMessage message2)
                              throws java.lang.Exception

Compare two ObjectMessage instances

Overrides:

compareObjectMessages in class AbstractMessageComparer

Parameters:

message1 - the message to compare

message2 - the message to compare

Returns:

true if the messages bodies contain references to the same objects

Throws:

java.lang.Exception - for any error

compareStreamMessages

public boolean compareStreamMessages(javax.jms.StreamMessage message1,
                                     javax.jms.StreamMessage message2)
                              throws java.lang.Exception

Compare two StreamMessage instances

Overrides:

compareStreamMessages in class AbstractMessageComparer

Parameters:

message1 - the message to compare

message2 - the message to compare

Returns:

true if the messages bodies contain references to the same objects

Throws:

java.lang.Exception - for any error

compareTextMessages

public boolean compareTextMessages(javax.jms.TextMessage message1,
                                   javax.jms.TextMessage message2)
                            throws java.lang.Exception

Compare two TextMessage instances

Overrides:

compareTextMessages in class AbstractMessageComparer

Parameters:

message1 - the message to compare

message2 - the message to compare

Returns:

true if the messages bodies contain references to the same objects

Throws:

java.lang.Exception - for any error
