All Implemented Interfaces:

java.lang.Cloneable

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

A FunctionNode which performs logical conjunction or the boolean function of AND.

Constructor Summary

AndFunction()
Construct an AndFunction with no children.

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

Method Summary

java.lang.Boolean	evaluate() Evaluating an AndFunction involves combining the evaluation of the children according to the rules of AND where if both children evaluate to true then the result will be true.
java.lang.String	getFunctionName() Get the unique name that identifies this function.

Constructor Detail

AndFunction

public AndFunction()

Construct an AndFunction with no children.

AndFunction

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

Construct an AndFunction with two children. When evaluated, if both children evaluate to true then the result will be true. All other combinations will return a result of false.

Parameters:

child1 - The first child node.

child2 - The second child node.

Method Detail

evaluate

public java.lang.Boolean evaluate()

Evaluating an AndFunction involves combining the evaluation of the children according to the rules of AND where if both children evaluate to true then the result will be true. All other combinations will return a result of 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 AndFunction which is AND.
