Constructor Detail

TangentFunction

public TangentFunction()

Construct a TangentFunction with no children.

TangentFunction

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

Construct a TangentFunction with one child. When evaluated, the child will be evaluated with tangent performed on the result.

Parameters:

child - The child which tangent will be performed on.

Method Detail

evaluate

public java.lang.Double evaluate()

Evaluating a TangentFunction involves evaluating the child then calculating the tangent of the result.

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 TangentFunction which is TAN.
