Class LinkedListWorkGroup

java.lang.Object
  |
  +--sjt.mgmt.LinkedListWorkGroup

All Implemented Interfaces:

WorkGroup

public class LinkedListWorkGroup

extends java.lang.Object

implements WorkGroup

This is implementation of the WorkGroup interface. In this case, the implementation is based on a java.util.LinkedList. As a FIFO type structure, the work is added to the bottom of the list, and removed from the top. Currently, no work load throttling is provided, meaning there is no mechanism to prevent the linked list from growing and growing and blowing memory. This defies one of the main points of thread management. Work load throttling will be added soon.

Since:

SJT 0.1
