public interface Actionable

The Actionable interface should be implemented by any class whose instances are intended to be executed by a task. The class must define a method of no arguments called action.

This interface is designed to provide a common protocol for objects that wish to execute code while they are active. For example, Actionable is implemented by class Task. Being active simply means that a task has been started and has not yet been stopped.

In addition, Actionable provides the means for a class to be active while not subclassing Task. A class that implements Actionable can run without subclassing Task by instantiating a Task instance and passing itself in as the target. In most cases, the Actionable interface should be used if you are only planning to override the action() method and no other Task methods. This is important because classes should not be subclassed unless the programmer intends on modifying or enhancing the fundamental behavior of the class.

Method Detail

action

void action()

When an object implementing interface Actionable is used to create a task, starting the task causes the object's action method to be called in that separately executing action.

The general contract of the method action is that it may take any action whatsoever.
