Method Detail

startInstance

public StateMachineInstance startInstance(int symIdx,
                                          int start)

Return a StateMachineInstance if the Symbol represented by the symbol index is valid as the initial symbol of the pattern. The returned StateMachineInstance will have its statepointer updated to show receipt of the specified symbol. This method should not be used outside of the package as it does no alphabet checks at all. It should be package-private except I cannot define an interface with such methods.

Parameters:

symIdx - alphabet index value for specified symbol.

Returns:

an instance of StateMachineInstance if symbol is valid otherwise null.

setListener

public void setListener(PatternListener listener)
