Constructor Detail

SimpleCurve

public SimpleCurve(String name)
            throws NoSuchMethodException

The constructor takes the name of the java method that represents the function. An example would be new SimpleCurve("java.lang.Math.sin")

The argument must be the name of a static method that takes a single double parameter and returns a double. If it doesn't meet this criteria an exception is thrown.

Parameters:: name - The fully qualified name of the function
Throws:: NoSuchMethodException - if the function doesn't exist, isn't static, doesn't take a double or doesn't return a double.
