方法详细资料

getSerializationType

public int getSerializationType()

指定者:

getSerializationType 在类中 Transition

isEpsilon

public boolean isEpsilon()

从类复制的说明: Transition

Determines if the transition is an "epsilon" transition.

The default implementation returns false.

覆盖:

isEpsilon 在类中 Transition

返回:

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)

指定者:
