          com.epochx.representation.dbl.CubeFunction

All Implemented Interfaces:

java.lang.Cloneable

public class CubeFunction
extends FunctionNode<java.lang.Double>

A FunctionNode which performs the arithmetic function of cube, that is - raising to the third power. It is equivalent to the PowerFunction where the second child is the double literal 3.0.

Constructor Summary

CubeFunction()
Construct a CubeFunction with no children.

CubeFunction(Node<java.lang.Double> child)
Construct a CubeFunction with one child.

Method Summary

java.lang.Double	evaluate() Evaluating a CubeFunction involves evaluating the child then raising the result to the power of 3.
java.lang.String	getFunctionName() Get the unique name that identifies this function.

Constructor Detail

CubeFunction

public CubeFunction()

Construct a CubeFunction with no children.

CubeFunction

public CubeFunction(Node<java.lang.Double> child)

Construct a CubeFunction with one child. When evaluated, the child will be evaluated with the result then raised to the power of 3.

Parameters:

child - The child which will be cubed.

Method Detail

evaluate

public java.lang.Double evaluate()

Evaluating a CubeFunction involves evaluating the child then raising the result to the power of 3.

Specified by:

evaluate in class Node<java.lang.Double>

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.Double>

Returns:

the unique name for the CubeFunction which is CUBE.
