Depending on the data type, the atomic manipulation classes in the Juc package can be divided into 4 classes.1. Basic type : Atomicinteger, Atomiclong, Atomicboolean;2. array type : Atomicintegerarray, Atomiclongarray, Atomicreferencearray;3. reference type : Atomicreference, Atomicstampedrerence, atomicmarkablereference;4. object's property modification type : Atomicintegerfieldupdater, Atomiclongfieldupdater, Atomicreferencefieldupdater.These classe

Nonatomic non-atomic properties are non-thread safe, suitable for small memory mobile devices (mobile phones, tablets ...)Atomic Atomic properties (thread safe, but requires a lot of resources) designed for multithreading, the default is to ensure that only one thread can write at the same time, which is itself a spin lock; write multiple read, single thread writ

In many cases we just need a simple, efficient, thread-safe increment-decrement scheme. Note that there are three conditions: simple, which means that it is easier for programmers to operate the underlying or implement as little as possible, and that efficiency means less resource consumption, faster process processing, and thread safety, which guarantees the correctness of the data in multiple threads. These three conditions look relatively simple, but they are difficult to achieve satisfactori

Currently, there is no formal introduction of the atomic type corresponding to the basic type in Swift 3.0. In MacOS and iOS, we can use the system's own Osatomic API for atomic manipulation processing. But this set of APIs can only be used on Apple's own platforms and we can't use them in Linux/freebsd, so I've encapsulated a set of atomic types and

Reprint: "The Art of Ava Concurrent Programming" chapter 7th When a program updates a variable, if multiple threads update this variable at the same time, it is possible to get a value other than expected, such as the variable i=1,a thread update i+1,b thread also updates i+1, after two thread operation may I not equal 3, but equal to 2. Because the A and B threads get the i in the update variable i is 1, this is the thread unsafe update operation, usually we will use synchronized to solve

Atomic classJava provides the Java.util.concurrent.atomic package (hereinafter referred to as the atomic package) from JDK 1.5, in this packageAtomic manipulation classes provide a simple, efficient, and thread-safe way to update a variable.Since there are many types of variables, there are 13 classes available in the atomic package, and 4 types of atoms are more

First, start with the atomic operationStart with a relatively simple atomic (Java.util.concurrent is a queue-based contract and the queue, in many cases, uses the atomic operation, so begin here first).In many cases we just need a simple, efficient, thread-safe increment-decrement scheme. Note that there are three conditions: Simple, means that the progr

java.util.concurrent.atomic Atomic Operation Class Pack=====java.util.concurrent.atomic Atomic Operation Class PackThis package provides a set of atomic variable classes. The basic feature is that in a multithreaded environment, when there are multiple threads executing the methods contained by instances of these classes at the same time, there is exclusivity, th

Atomic operation This is the cliché of Java multithreaded programming. Atomic operations are operations that are not interrupted by thread scheduling mechanisms that, once started, run to the end without any context switch (switching to another thread). Of course JS is single-threaded, so there is no thread interrupt so, I just borrowed a concept from Java. If a section of JS code in the implementation of
