HandleInput()

template<class F , class R >

void TMPWorkerExecutor< F, void, R >::HandleInput ( MPCodeBufPair &  msg )

inlinevirtual

Handle a message with an EMPCode.

This method is called upon receiving a message with a code >= 1000 (i.e. EMPCode). It handles the most generic types of messages.
Classes inheriting from TMPWorker should implement their own HandleInput function, that should be able to handle codes specific to that application.
The appropriate version of the HandleInput method (TMPWorker's or the overriding version) is automatically called depending on the message code.

Reimplemented from TMPWorker.
