Detailed Description

Create a custom unary function that checks if a number is prime.

Instead of inheriting from the top-level Function class, it is easier in most cases to descend from lower classes, which provide a few more functionalities. For a function that takes a single argument, it is wise to extend UnaryFunction.

instance

final transient IsPrime functions.IsPrime.instance = new IsPrime()

static

This is optional.

Since a Function object is stateless, the same instance can be used everywhere it is needed. Therefore, it is recommended to enforce the existence of a single instance by making the function's constructor private, and by making public a static field pointing to an instance of the function. By convention, you are encouraged to use the name "instance" for this field.
