public class CompareNode
extends Node

A compare-node is where the action takes place in an expression tree. All other nodes just wire up the compare-nodes.

Constructor Summary

CompareNode(Node parent, ParseToken expression, CapNode cap)
This creates a new CompareNode

Method Summary

ParseToken	getExpression() This method returns the expression
java.lang.String	getTreeName() This returns the name of the construct unique to the tree the node is in.
java.lang.String	toString()
java.lang.String	whereDoIGoOnFail()
java.lang.String	whereDoIGoOnFail(Node whichChildAmI)
java.lang.String	whereDoIGoOnPass()
java.lang.String	whereDoIGoOnPass(Node whichChildAmI) When a child node finishes its processing it can either have passed or failed and needs a destination to jump to (another compare-node or the pass/fail blocks).

Constructor Detail

CompareNode

public CompareNode(Node parent,
                   ParseToken expression,
                   CapNode cap)

This creates a new CompareNode

Parameters:

parent - the parent node

expression - the expression to generate code for

cap - the root of the expression

Method Detail

getTreeName

public java.lang.String getTreeName()

This returns the name of the construct unique to the tree the node is in.

Returns:

the tree's name

getExpression

public ParseToken getExpression()

This method returns the expression

Returns:

the expression

whereDoIGoOnPass

public java.lang.String whereDoIGoOnPass()

whereDoIGoOnFail

public java.lang.String whereDoIGoOnFail()

whereDoIGoOnPass

public java.lang.String whereDoIGoOnPass(Node whichChildAmI)

Description copied from class: Node

When a child node finishes its processing it can either have passed or failed and needs a destination to jump to (another compare-node or the pass/fail blocks). This method returns the next place.

Specified by:

whereDoIGoOnPass in class Node

Parameters:

whichChildAmI - which child I am (AND and OR have multiple children)

Returns:

the name of the next jump destination

whereDoIGoOnFail

public java.lang.String whereDoIGoOnFail(Node whichChildAmI)

Specified by:

whereDoIGoOnFail in class Node

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
