getSerializationType
public int getSerializationType()- Specified by:

-
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 classTransition
- 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.
