1、ArrayBlockingQueue ArrayBlockingQueue是由数组构成的有界阻塞队列,支持FIFO的次序对元素进行排序。 这是一个典型的有界缓冲结构,可指定大小存储元素,供生产线程插入,供消费线程获取,但注意,容量一旦指定,便不可修改。 队列空时尝试take操作和队列满时尝试put操作都会阻塞执行操作的线程。
ustd provides minimal and highly portable implementations of the following classes: ustd::array, a lightweight c++11 array implementation (ustd_array.h). ustd::queue, a lightweight c++11 queue implementation (ustd_queue.h). ustd::map, a lightweight c++11 map implementation (ustd_map.h)...
A bounded blocking queue backed by an array. This queue orders elements FIFO (first-in-first-out). The head of the queue is that element that has been on the queue the longest time. The tail of the queue is that element that has been on the queue the shortest time. New elements are...
