Method Detail

iterator

public Iterator<ITask> iterator()

Specified by:

iterator in interface Iterable<ITask>

addTask

public boolean addTask(ITask t)

Description copied from interface: ITaskSet

Add a task to the task set

Specified by:

addTask in interface ITaskSet

Specified by:

addTasks in interface ITaskSet

getActiveTasks

public SortedSet<ITask> getActiveTasks(long date)

Description copied from interface: ITaskSet

return a subset containing active tasks, ordered consistently with the scheduling policy used. Note that the ordering may be inconsistent with Task.equals();

Specified by:

getActiveTasks in interface ITaskSet

Returns:

the active tasks
