Interface Task

All Superinterfaces:
java.io.Serializable
All Known Implementing Classes:
TaskInstanceBean

public interface Task
extends java.io.Serializable

Accesses the properties of a task instance.

A task represents a piece of work. It contains all data that is necessary to get the job done. For example, a task that is associated to a group of potential owners allows a person that belongs to the group to claim the task, work on the task, and to complete the task.
