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

A FunctionNode which performs the logical operation of NOR that is equivalent to the negation of logical OR or NOT OR.


Constructor Summary
NorFunction()
          Construct a NorFunction with no children.
NorFunction(Node<java.lang.Boolean> child1, Node<java.lang.Boolean> child2)
          Construct a NorFunction with two children.
 
Method Summary
 java.lang.Boolean evaluate()
          Evaluating a NorFunction involves combining the evaluation of the children according to the rules of NOR where if both children evaluate to false then the result will be true.

Constructor Detail

NorFunction

public NorFunction()
Construct a NorFunction with no children.


NorFunction

public NorFunction(Node<java.lang.Boolean> child1,
                   Node<java.lang.Boolean> child2)
Construct a NorFunction with two children. When evaluated, if both children evaluate to false 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 a NorFunction involves combining the evaluation of the children according to the rules of NOR where if both children evaluate to false 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 NorFunction which is NOR.
