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) $
