Class AbstractNode

java.lang.Object
  lab7.AbstractNode

All Implemented Interfaces:

NodeDumpable, ReflectiveVisitable

Direct Known Subclasses:

CastNode

public abstract class AbstractNode
extends java.lang.Object
implements ReflectiveVisitable, NodeDumpable

All AST nodes are subclasses of this node. This node knows how to link itself with other siblings and adopt children. Each node gets a node number to help identify it distinctly in an AST.
