Interface InvocationEngine

All Known Implementing Classes:

DefaultInvocationEngine

public interface InvocationEngine

Orchestrates the process of getting tokens and federation contexts needed to invoke a service. Some service invocations require security tokens (such as an X.509 identity or a SAML attribute token) or a federation context (such as an SLA under which the service is to be used). An InvocationEngine collects these extra items and attaches them to the actual SOAP message.

Method Summary

Transport	getTransport() Get the transport used for sending SOAP messages.
Object	invoke(org.apache.axis.message.addressing.EndpointReferenceType target, RemoteMethod method, Object[] arguments) Invoke a SOAP operation, adding any required tokens and federation headers.
