All Implemented Interfaces:

TreeNode

public abstract class AbstractNode
extends Object
implements TreeNode

A node in the parse tree.

Cytoscape Backwards Compatibility (Abstract Class): This class is abstract and meant to be extended by users. This means that we may add methods for minor version updates. Methods will only be removed for major version updates.

Constructor Summary

AbstractNode(int sourceLocation)

Method Summary

abstract void	genCode(Stack<CodeAndSourceLocation> codeStack) Generated code for this node and pushes it onto the execution stack.
abstract TreeNode	getLeftChild() Returns the left child if it exists or null if it doesn't.
abstract TreeNode	getRightChild() Returns the right child if it exists or null if it doesn't.
int	getSourceLocation() Returns the start of the location in the equation where the code was found that was turned into a node in the parse tree.
abstract Class	getType() Returns the type of this node.
abstract String	toString() Returns s String representation of this node.
