C++ implementation This article is about queue implementation using array in C++. Queue as an Abstract data Type Queue is an ordered data structure to store datatypes in FIFO (First in First Out) order. That means the element which enters first is first to exit(processed). It’s like the ...
Queue是一个 线性数据结构 它用作根据 FIFO(FIFO)原则插入和删除的对象的容器。 Queue主要有三个操作: enqueue, dequeue,和 peek.我们已经介绍了这些操作和Queue数据结构的 C 实现,使用 数组 和链表.在这篇文章中,我们将介绍使用类和 STL 在 C++ 中实现Queue。 C++ 中的以下Queue实现包括以下操作: Enqueue: ...

BufferQueue的核心逻辑是生产者消费者逻辑,在BufferQueue这个生产者消费者框架中, BufferQueuecore可以理解为数据缓冲区的管理者,代码逻辑在BufferQueue.cpp和BufferQueuecore.cpp中。 它的原始消费者是BufferQueueConsumer,它的原始生产者是BufferQueueProducer。 那么BufferQueue.cpp 和BufferQueuecore.cpp是什么样的关系呢,可以理...

Implementation Operation The push/pop operations are defined successful when compare_exchange successed on the internal buffer's entries. The write / read indexes are changed also using atomic compare_exchange as second step of the operation.

Une Queue est unstructure de données linéairequi sert de conteneur d'objets qui sont insérés et retirés selon le principe FIFO (First–In, First–Out). La Queue a trois opérations principales :enqueue,dequeue, etpeek. Nous avons déjà couvert ces opérations et l'implémentation C de ...
