getVocabulary

public Vocabulary getVocabulary()

Description copied from class: Recognizer

Get the vocabulary used by the recognizer.

Overrides:

getVocabulary in class Recognizer<Integer,LexerATNSimulator>

Returns:

A Vocabulary instance providing information about the vocabulary used by the grammar.
