Package org.antlr.v4.runtime.tree

Class ErrorNodeImpl

java.lang.Object

org.antlr.v4.runtime.tree.TerminalNodeImpl

org.antlr.v4.runtime.tree.ErrorNodeImpl

All Implemented Interfaces:

ErrorNode, ParseTree, SyntaxTree, TerminalNode, Tree

public class ErrorNodeImpl
extends TerminalNodeImpl
implements ErrorNode

Represents a token that was consumed during resynchronization rather than during a valid match operation. For example, we will create this kind of a node during single token insertion and deletion as well as during "consume until error recovery set" upon no viable alternative exceptions.
