## Detailed Description

### template<typename Task = prio_task_func>
class boost::threadpool::prio_scheduler< Task >

SchedulingPolicy which implements prioritized ordering.

This container implements a scheduling policy based on task priorities. The task with highest priority will be the first to be removed. It must be possible to compare two tasks using operator<.

Parameters

  Task | A function object which implements the operator() and operator<. operator< must be a partial ordering.

## Member Typedef Documentation

template<typename Task = prio_task_func>

typedef Task boost::threadpool::prio_scheduler< Task >::task_type

Indicates the scheduler's task type.

Definition at line 196 of file scheduling_policies.hpp.

## Member Function Documentation

template<typename Task = prio_task_func>

void boost::threadpool::prio_scheduler< Task >::clear | ( |  | ) |
| inline

Removes all tasks from the scheduler.

template<typename Task = prio_task_func>

bool boost::threadpool::prio_scheduler< Task >::empty | ( |  | ) | const
| inline

Checks if the scheduler is empty.

Returns
  true if the scheduler contains no tasks, false otherwise.

Remarks
  Is more efficient than size() == 0.

void boost::threadpool::prio_scheduler< Task >::pop | ( |  | ) |
| inline

Removes the task which should be executed next.

Definition: scheduling_policies.hpp:199
template<typename Task = prio_task_func>

bool boost::threadpool::prio_scheduler< Task >::push | ( | task_type const & | task | ) |
| inline

Adds a new task to the scheduler.

Parameters

  task | The task object.

Returns
  true, if the task could be scheduled and false otherwise.

Definition at line 207 of file scheduling_policies.hpp.

208 {
209 m_container.push(task);
210 return true;

size_t boost::threadpool::prio_scheduler< Task >::size | ( |  | ) | const
| inline

Gets the current number of tasks in the scheduler.

Returns
  The number of tasks.

Remarks
  Prefer empty() to size() == 0 to check if the scheduler is empty.
