IStateChangeHandler

public class BasicStateChangeHandler
extends java.lang.Object
implements IStateChangeHandler

Provides a basic reporting mechanism for logging state changes during run-time. This allows for some basic debugging of state models and would not normally be used in production code, so by default no handler is associated with an Engine and there will be no output.

This handler reports state change information on the standard output stream.
