public boolean isEpsilon()

Overrides org.antlr.v4.runtime.atn.Transition.isEpsilon.

Doc from org.antlr.v4.runtime.atn.Transition.isEpsilon.

Determines if the transition is an "epsilon" transition.

The default implementation returns false.

Returns:boolean

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.
