Constructor Detail

HyperbolicCosineFunction

public HyperbolicCosineFunction()
Construct a HyperbolicCosineFunction with no children.


HyperbolicCosineFunction

public HyperbolicCosineFunction(Node<java.lang.Double> child)
Construct a HyperbolicCosineFunction with one child. When evaluated, the child will first be evaluated with hyperbolic cosine performed on the result.

Parameters:
child - The child which hyperbolic cosine will be performed on.
Method Detail

evaluate

public java.lang.Double evaluate()
Evaluating an HyperbolicCosineFunction involves calculating the hyperbolic cosine of the child once it has also 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 HyperbolicCosineFunction which is COSH.
