java.lang.Cloneable

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

A MinFunction which performs the simple comparison function of determining which of 2 numbers is smaller, as per the boolean less-than function.

Constructor Summary

MinFunction()
Construct a MinFunction with no children.

MinFunction(Node<java.lang.Double> child1, Node<java.lang.Double> child2)
Construct a MinFunction with two child.

Method Summary

java.lang.Double	evaluate() Evaluating a MinFunction involves evaluating the children then comparing and returning which ever is the smaller of the 2 evaluated children.
java.lang.String	getFunctionName() Get the unique name that identifies this function.

Constructor Detail

MinFunction

public MinFunction()

Construct a MinFunction with no children.

MinFunction

public MinFunction(Node<java.lang.Double> child1,
                   Node<java.lang.Double> child2)

Construct a MinFunction with two child. When evaluated, the children will both be evaluated with the smaller of the two returned as the result.

Parameters:

child1 - The first child node for comparison.

child2 - The second child node for comparison.

Method Detail

evaluate

public java.lang.Double evaluate()

Evaluating a MinFunction involves evaluating the children then comparing and returning which ever is the smaller of the 2 evaluated children.

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 MinFunction which is MIN.
