NAME

       __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.

SYNOPSIS

       #include <queue.h>

   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().

Detailed Description

       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.
