This class abstracts the process of identifying the wsdl operation from a SOAP Message request. This is primarily for dispatching the request messages to an endpoint method. Different implementations of WSDLOperationFinder are used underneath to identify the wsdl operation based on if AddressingFeature is enabled or not.
