Public Member Functions¶

_RestrictedBoundedConcurrentQueue (_SequenceIndex __max_size)
Constructor. Not to be called concurrent, of course. ~_RestrictedBoundedConcurrentQueue ()
Destructor. Not to be called concurrent, of course. bool pop_back (_Tp &__t)
Pops one element from the queue at the front end. Must not be called concurrently with pop_front(). bool pop_front (_Tp &__t)
Pops one element from the queue at the front end. Must not be called concurrently with pop_front(). void push_front (const _Tp &__t)
Pushes one element into the queue at the front end. Must not be called concurrently with pop_front().

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

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

Constructor. Not to be called concurrent, of course.

Parameters

References __gnu_parallel::__encode2().

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

Destructor. Not to be called concurrent, of course.

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().

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().

References __gnu_parallel::__compare_and_swap(), __gnu_parallel::__decode2(), and __gnu_parallel::__encode2().

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