@FunctionalInterface
Type Parameters
<P>
The type of the argument provided to the call method.
<R>
The type of the return type of the call method.
The Callback interface is designed to allow for a common, reusable interface to exist for defining APIs that requires a call back in certain situations.

Callback is defined with two generic parameters: the first parameter specifies the type of the object passed in to the call method, with the second parameter specifying the return type of the method.
