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
_TpContained element type.

Member Function Documentation

◆ pop_back()

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

Pops one element from the queue at the front end. Must not be called concurrently with pop_front().

◆ pop_front()

template<typename _Tp >
bool __gnu_parallel::_RestrictedBoundedConcurrentQueue< _Tp >::pop_front ( _Tp &  __t)
inline

Pops one element from the queue at the front end. Must not be called concurrently with pop_front().

Definition at line 100 of file queue.h.

◆ push_front()

template<typename _Tp >
void __gnu_parallel::_RestrictedBoundedConcurrentQueue< _Tp >::push_front ( const _Tp &  __t)
inline

Pushes one element into the queue at the front end. Must not be called concurrently with pop_front().
