bexee.core
Interface ProcessController

All Known Implementing Classes:

ProcessControllerImpl

public interface ProcessController

The ProcessController is the core of the engine and contains the execution logic for every BPEL activity.

The ProcessController needs to be thread-safe as several threads may use it simultaneously.

The current version of bexee doesn't support all possible BPEL activities. This is the reason, why there is a process(ProcessInstance, Activity) method, it's a substitute for all unimplemented activities. When implementing an Activity, the implementor has to add a method process(ProcessInstance, NewlyImplActivity) to this interface and implement it in all implementing classes.
