INameNode, ISourcePositionHolder

Direct Known Subclasses:

KeywordRestArgNode, RestArgNode, TypedArgumentNode

public class ArgumentNode
extends Node
implements INameNode

Simple Node for named entities. Things like the name of a method will make a node for the name. Also local variables will make a ArgumentNode. In the case of a local variable we will also keep a list of it's location.
