Detailed Description

A policy describes how to execute a task.

Description

When executing a task there are several ways to cope with failure. An application might require to try to execute the task again, another one might need to stop when running them too many times.

A policy specifies the rules of executing a task.

The Concept

A class to qualify for the Policy concept needs to define a execute() method. The method need to take a callable object (which implements the Task concept) and the arguments to invoke the callable with. It needs to return a Failable.
