Class PooledMarshalledInvocation

java.lang.Object
  org.jboss.invocation.Invocation
      org.jboss.invocation.MarshalledInvocation
          org.jboss.invocation.pooled.interfaces.PooledMarshalledInvocation

All Implemented Interfaces:: Externalizable, Serializable

public class PooledMarshalledInvocation
extends MarshalledInvocation
implements Externalizable

The MarshalledInvocation is an invocation that travels. As such it serializes its payload because of lack of ClassLoader visibility. As such it contains Marshalled data representing the byte[] of the Invocation object it extends Besides handling the specifics of "marshalling" the payload, which could be done at the Invocation level the Marshalled Invocation can hold optimization and needed code for distribution for example the TransactionPropagationContext which is a serialization of the TX for distribution purposes as well as the "hash" for the methods that we send, as opposed to sending Method objects. Serialization "optimizations" should be coded here in the externalization implementation of the class

Initial check-in

20020113 Sacha Labourey:

Make Externalizable calls (writeExternal) idempotent: until now, serialization on a MarshalledInvocation could only performed once (transaction was removed and METHOD type was modified). If another call was re-using the same object (in clustering for example), the call was making a ClassCastException because of the changed METHOD type in the Map that occured in the previous call to writeExternal)

20020911 Bill Burke:

Optimize access to certain variables. Avoid hash lookups.
