Method Detail

getSerializationType

public int getSerializationType()

Specified by:

getSerializationType in class Transition

isEpsilon

public boolean isEpsilon()

Description copied from class: Transition

Determines if the transition is an "epsilon" transition.

The default implementation returns false.

Overrides:

isEpsilon in class Transition

Returns:

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.

matches

public boolean matches(int symbol,
              int minVocabSymbol,
              int maxVocabSymbol)

Specified by:

matches in class Transition

toString

public String toString()

Overrides:

toString in class Object
