Class LiteralNode

java.lang.Object

org.jruby.ast.Node

org.jruby.ast.LiteralNode

All Implemented Interfaces:

InvisibleNode, ISourcePosition, ISourcePositionHolder, PositionAware

public class LiteralNode
extends Node
implements InvisibleNode

This is not a node in the classic sense in that it has no defined or interpret method which can be called. It just stores the position of the literal and the name/value of the literal. We made it a node so that the parser needs to work less hard in its productions. dynamic literals are nodes and by having literals also be nodes means they have a common subtype which is not Object. Used by alias and undef.
