Transition
The default implementation returns false
.
isEpsilon
in class Transition
true
if traversing this transition in the ATN does not
consume an input symbol; otherwise, false
if traversing this
transition consumes (matches) an input symbol.public boolean matches(int symbol, int minVocabSymbol, int maxVocabSymbol)
