__gnu_parallel__RestrictedBoundedConcurrentQueue.3cxx

NAME

__gnu_parallel::_RestrictedBoundedConcurrentQueue -

Double-ended queue of bounded size, allowing lock-free atomic access. push_front() and pop_front() must not be called concurrently to each other, while pop_back() can be called concurrently at all times. empty(), size(), and top() are intentionally not provided. Calling them would not make sense in a concurrent setting.

SYNOPSIS

Public Member Functions

_RestrictedBoundedConcurrentQueue (_SequenceIndex __max_size)

~_RestrictedBoundedConcurrentQueue ()

bool pop_back (_Tp &__t)

bool pop_front (_Tp &__t)

void push_front (const _Tp &__t)

Detailed Description

template<typename _Tp> class __gnu_parallel::_RestrictedBoundedConcurrentQueue< _Tp >

Double-ended queue of bounded size, allowing lock-free atomic access. push_front() and pop_front() must not be called concurrently to each other, while pop_back() can be called concurrently at all times. empty(), size(), and top() are intentionally not provided. Calling them would not make sense in a concurrent setting.

Parameters:

_Tp Contained element type.

Constructor & Destructor Documentation

template<typename _Tp> __gnu_parallel::_RestrictedBoundedConcurrentQueue< _Tp >::_RestrictedBoundedConcurrentQueue (_SequenceIndex __max_size) [inline]

Constructor. Not to be called concurrent, of course. Parameters:

_M_max_size Maximal number of elements to be contained.

Definition at line 68 of file queue.h.

template<typename _Tp> __gnu_parallel::_RestrictedBoundedConcurrentQueue< _Tp >::~_RestrictedBoundedConcurrentQueue () [inline]

Destructor. Not to be called concurrent, of course.

Definition at line 77 of file queue.h.

Member Function Documentation

template<typename _Tp> bool __gnu_parallel::_RestrictedBoundedConcurrentQueue< _Tp >::pop_back (_Tp & __t) [inline]
