Method Details
- 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.
