Constructor Detail

ArcCosineFunction

public ArcCosineFunction()

Construct an ArcCosineFunction with no children.

ArcCosineFunction

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

Construct an ArcCosineFunction with one child. When evaluated, the child will be evaluated with arccosine performed on the result.

Parameters:

child - The child which arccosine will be performed on.

Method Detail

evaluate

public java.lang.Double evaluate()

Evaluating an ArcCosineFunction involves calculating the arccosine of the child once it's been evaluated.

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 ArcCosineFunction which is ACOS.
