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 Function Documentation

template<typename Task = prio_task_func>

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

inline

Removes all tasks from the scheduler.

Definition at line 248 of file scheduling_policies.hpp.

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.

Definition at line 241 of file scheduling_policies.hpp.

template<typename Task = prio_task_func>

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

inline

Removes the task which should be executed next.

Definition at line 215 of file scheduling_policies.hpp.

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.

template<typename Task = prio_task_func>

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.

Definition at line 232 of file scheduling_policies.hpp.

template<typename Task = prio_task_func>

task_type const& boost::threadpool::prio_scheduler< Task >::top ( ) const

inline

Gets the task which should be executed next.

Returns

The task object to be executed.

Definition at line 223 of file scheduling_policies.hpp.
