public interface AsyncSOAPInvokeState
Represents a stored/pending asynchronous SOAP operation invocation. Objects
implementing this interface are placed on the buffering (WS-RM or just async)
queue during processing. This is done to maintain the state of the invocation
while decoupling the caller from the actual work for the invocation.
Customers can use this interface to interrogate failed async messages that
they have accumulated in an error queue associated with the buffering queue
(if any, and max retries is set on the buffering queue).
