org.fabric3.implementation.proxy.jdk.wire.AbstractCallbackInvocationHandler<T>

org.fabric3.implementation.proxy.jdk.wire.MultiThreadedCallbackInvocationHandler<T>

All Implemented Interfaces:

java.lang.reflect.InvocationHandler

public class MultiThreadedCallbackInvocationHandler<T>
extends AbstractCallbackInvocationHandler<T>

Responsible for dispatching to a callback service from multi-threaded component instances such as composite scope components. Since callback proxies for multi-threaded components may dispatch to multiple callback services, this implementation must determine the correct target service based on the current CallbackReference. For example, if clients A and A' implementing the same callback interface C invoke B, the callback proxy representing C must correctly dispatch back to A and A'. This is done by recording the callback URI as the forward invoke is made.

Constructor Detail

MultiThreadedCallbackInvocationHandler

public MultiThreadedCallbackInvocationHandler(java.util.Map<java.lang.String,java.util.Map<java.lang.reflect.Method,org.fabric3.spi.container.wire.InvocationChain>> mappings)

Constructor. In multi-threaded instances such as composite scoped components, multiple forward invocations may be received simultaneously. As a result, since callback proxies stored in instance variables may represent multiple clients, they must map the correct one for the request being processed on the current thread. The mappings parameter keys a callback URI representing the client to the set of invocation chains for the callback service.

Parameters:

mappings - the callback URI to invocation chain mappings
