Examples of InvocationConfiguration

org.apache.tuscany.core.invocation.InvocationConfiguration
org.apache.tuscany.core.wire.InvocationConfiguration
Contains a source- or target-side invocation pipeline for a service operation. The runtime framework creates invocation chains on a per-operation, per-service basis. Further, invocation chains are further distinguished by being part of the source or target sides of a wire. Chains are "bridged" together by the runtime by a set of {@link org.apache.tuscany.core.builder.WireBuilder}s with the source-side holding references to the target.
InvocationChains are managed by {@link WireConfiguration}s, which are used by {@link org.apache.tuscany.core.wire.WireFactory}s to buildSource wires and proxies.
Invocation configurations must contain at least one interceptor and may have 0 to N handlers. Handlers process a wire request or response in a one-way fashion. A typical wire sequence where interceptors and handlers are configured for both the source and target-side will proceed as follows:
```
  The first source interceptor will be called with a message, which will in turn invoke the next interceptor in the chain 
The last source interceptor, which must be of type  {@link org.apache.tuscany.core.wire.impl.RequestResponseInterceptor} if there are handlers present, will be invoked. The RRinterceptor will in turn pass the message to a  {@link MessageChannel} which will invoke all source-side request handlers.
The RR interceptor will then invoke the target-side request MessageChannel. 
The last source-side handler, an instance of  {@link org.apache.tuscany.core.wire.impl.MessageDispatcher}, will invoke the first source-side interceptor, which in turn will pass the message down the target-side interceptor chain. 
If the target is a component instance the last target-side interceptor, an instance of {@link org.apache.tuscany.core.wire.impl.InvokerInterceptor} will retrieve the {@link TargetInvoker} from the message andcall it to invoke the operation on a target instance. TargetInvokers are help by the source proxy to enable optimizations such as caching of target instances. 
 The response is returned up the wire stack until it reaches the source-side RequestResponseInterceptor, which invokes the target and source-side response channels respectively. 
The response is then passed back up the rest of the wire stack. 
 
```
The source-to-target bridge may be constructed in any of the following ways:
```
  Source handler-to-target handler 
Source handler-to-target interceptor 
Source interceptor-to-target handler 
Source interceptor-to-target interceptor 
 
```
In some scenarios, a service proxy may only contain target-side invocaton chains, for example, when a service is resolved through a locate operation by a non-component client. In this case, there will be no source-side wire chains and the target invoker will be held by the target-side and passed down the pipeline. @version $Rev: 408581 $ $Date: 2006-05-21 23:34:24 -0700 (Sun, 21 May 2006) $ @see org.apache.tuscany.core.builder.WireBuilder @see WireFactory @see TargetInvoker @see org.apache.tuscany.core.wire.impl.MessageDispatcher
