Constructor Detail

MultiplyFunction

public MultiplyFunction()

Construct a MultiplyFunction with no children.

MultiplyFunction

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

Construct a MultiplyFunction with 2 children. When evaluated, both children will be evaluated and then multiplied together.

Parameters:

child1 - The first child node.

child2 - The second child node.

Method Detail

evaluate

public java.lang.Double evaluate()

Evaluating a MultiplyFunction involves multiplying the result of evaluating both 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 MultiplyFunction which is MUL.
