All Implemented Interfaces:

java.lang.Cloneable

public class XorFunction
extends FunctionNode<java.lang.Boolean>

A FunctionNode which performs exclusive disjunction, also known as exclusive OR.

Constructor Summary

XorFunction()
Construct an XorFunction with no children.

XorFunction(Node<java.lang.Boolean> child1, Node<java.lang.Boolean> child2)
Construct an XorFunction with two children.

Method Summary

java.lang.Boolean	evaluate() Evaluating an XorFunction involves evaluating both children.
java.lang.String	getFunctionName() Get the unique name that identifies this function.

Constructor Detail

XorFunction

public XorFunction()

Construct an XorFunction with no children.

XorFunction

public XorFunction(Node<java.lang.Boolean> child1,
                   Node<java.lang.Boolean> child2)

Construct an XorFunction with two children. When evaluated, if either child evaluates to true (but not both) then the result will be true, otherwise the result will be false.

Parameters:

child1 - The first child node.

child2 - The second child node.

Method Detail

evaluate

public java.lang.Boolean evaluate()

Evaluating an XorFunction involves evaluating both children. If either child evaluates to true (but not both) then the result will be true, otherwise the result will be false.

Specified by:

evaluate in class Node<java.lang.Boolean>

Returns:

The result of evaluating the candidate program.

getFunctionName

public java.lang.String getFunctionName()

Get the unique name that identifies this function.

Specified by:

getFunctionName in class FunctionNode<java.lang.Boolean>

Returns:

the unique name for the XorFunction which is XOR.
