Interface OclStateAdapter

public interface OclStateAdapter

This interface must be implemented if OclAnys operation oclInState is used. The implementation must be able to check the state of objects. That can be done either in a object dependent way, or in object independent way if the state machines are generated by a CASE tool and that tools generation schemes permits a general solution. If the proposed way of state evaluation through OclStates String seems inadequate for performance reasons, consider creating a more efficient subclass of OclState, and a subclass of DefaultOclFactory that uses these custom OclStates.
