TaskQueue

java.lang.Object
- com.sun.enterprise.util.collection.BlockingQueue

public class TaskQueue extends com.sun.enterprise.util.collection.BlockingQueue

TaskQueue provides the user the ability to queue his objects without worring about the usage of the TaskQueue by the ThreadPool. The responsibility of the Task creation is now delegated to the TaskFactory. TaskFactory will create or pool the task objects that wrap the users object. The tasks need to implement the Serviceable interface

Fields Summary
private TaskFactory
taskFactory
Constructors Summary
public TaskQueue(TaskFactory factory)
Create a TaskQueue that has an infinite queuelength with the specified timeout.
param
The maximum time remove() will block.
see
remove()
super(); taskFactory = factory;
public TaskQueue(int queueLimit, TaskFactory factory)
Create a TaskQueue that has the specified queue limit with the specified timeout.
param
The maximum time remove() will block.
param
The queue length after which TooManyTasksException is thrown.
see
remove()
super(queueLimit); taskFactory = factory;
Methods Summary
public void add(int index, java.lang.Object object)
Add the job at the specified position. Probably based on priority?
super.add(index, taskFactory.createTask(object));
public void addAll(java.util.ArrayList arrayList)
for (int i=0; i < arrayList.size(); i++) { Object o = taskFactory.createTask(arrayList.get(i)); arrayList.set(i, o); } super.addAll(arrayList);
public void addFirst(java.lang.Object o)
Add to the head of the queue. Probably a high priority job?
super.addFirst(taskFactory.createTask(o));
public void addFirst(Servicable ser)
Add to the head of the queue. Probably a high priority job?
super.addFirst(ser);
public void addLast(java.lang.Object o)
Add to the tail of the queue.
super.addLast(taskFactory.createTask(o));
public void addLast(Servicable ser)
Add to the tail of the queue.
super.addLast(ser);
public void destroyTask(java.lang.Object o)
Hook to enable factory to deleteTask. The deleteTask can potentially return the object to some pool
taskFactory.deleteTask(o);
