Examples of InvocationChain

org.apache.tuscany.sca.invocation.InvocationChain
A wire consists of 1..n invocation chains associated with the operations of its source service contract.
Invocation chains may contain Interceptors that process invocations.
A Message is used to pass data associated with an invocation through the chain. @version $Rev: 632064 $ $Date: 2008-02-28 17:18:51 +0000 (Thu, 28 Feb 2008) $
org.apache.tuscany.spi.wire.InvocationChain
An inbound or outbound invocation pipeline for a service operation. Wires consist of 1..n invocation chains associated with the operations of the service contract the wire represents. Invocation chains are associated with the outbound or inbound side of a wire are bridged or "connected" when an assembly is processed. Outbound chains are only connected to inbound chains and vice versa.
Invocation chains contain at least one {@link Interceptor} that process invocations in an around-style manner. Insome scenarios, a service proxy may only contain inbound invocation chains, for example, when a service is resolved through a locate operation by a non-component client. In this case, there will be no outbound invocation chains and the target invoker will be held by the target-side and passed down the pipeline.
A {@link Message} is used to pass data associated with an invocation through the chain. Messages containa {@link TargetInvoker} responsible for dispatching to a target instance and may be cached on the source-side.Caching allows various optimizations such as avoiding target instance resolution when the client-side lifecycle scope is a shorter duration than the target. @version $Rev: 441749 $ $Date: 2006-09-08 23:55:02 -0700 (Fri, 08 Sep 2006) $
