Description copied from interface: Sender

Returns the address that the Sender instance will send Message objects to. The value returned from this method is control by the configuration that was used to create the sender.

• If the Sender is configured as an anonymous sender then this method returns null.
• If the Sender was created with the dynamic sender methods then the method will return the dynamically created address once the remote has attached its end of the sender link. Due to the need to await the remote peer to populate the dynamic address this method will block until the open of the sender link has completed.
• If neither of the above is true then the address returned is the address passed to the original Session.openSender(String) or Session.openSender(String, SenderOptions) methods.

Specified by:
