Package fsa_recognizer :: Module class_fsa_recognize :: Class fsa_recognizer

Class fsa_recognizer

Known Subclasses:

Class for finite-state recognizers.

Each fsa_recognizer instance has an fsa stored in self.fsa, which must be supplied at initialization time.

The recognize method defined here is just a stub for recognize methods that must be defined for the various subclasses of fsa_recognizer. Such stubs are sometimes called abstract methods.
