Detailed Description

template<typename Task = task_func>
class boost::threadpool::fifo_scheduler< Task >

SchedulingPolicy which implements FIFO ordering.

This container implements a FIFO scheduling policy. The first task to be added to the scheduler will be the first to be removed. The processing proceeds sequentially in the same order. FIFO stands for "first in, first out".

Parameters

Task	A function object which implements the operator()(void).

Member Typedef Documentation

template<typename Task = task_func>

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

Indicates the scheduler's task type.

Definition at line 48 of file scheduling_policies.hpp.

Member Function Documentation

template<typename Task = task_func>

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

inline

Removes all tasks from the scheduler.

Definition at line 100 of file scheduling_policies.hpp.

    {   
      m_container.clear();
    } 

template<typename Task = task_func>

bool boost::threadpool::fifo_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 93 of file scheduling_policies.hpp.

    {
      return m_container.empty();
    }

template<typename Task = task_func>

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

inline

Removes the task which should be executed next.

Definition at line 67 of file scheduling_policies.hpp.

    {
      m_container.pop_front();
    }

template<typename Task = task_func>

bool boost::threadpool::fifo_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 59 of file scheduling_policies.hpp.

    {
      m_container.push_back(task);
      return true;
    }

template<typename Task = task_func>

size_t boost::threadpool::fifo_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 84 of file scheduling_policies.hpp.

    {
      return m_container.size();
    }

template<typename Task = task_func>

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

inline

Gets the task which should be executed next.

Returns

The task object to be executed.

Definition at line 75 of file scheduling_policies.hpp.

    {
      return m_container.front();
    }

Member Data Documentation

template<typename Task = task_func>

std::deque<task_type> boost::threadpool::fifo_scheduler< Task >::m_container

protected

Internal task container.
