Each of the MessageStore implementations provide different back end storage for their messagess messages and so would need a different tool to be able to interrogate their contents. What this tool does is to utilise the Java broker code base to access the contents of the storage providing the user with a consistent means to inspect the storage contents. The tool allows the current messages in the store to be inspected and copied/moved between queues.
