First, Reentranlock I believe we have all used Reentranlock,reentranlock is the concurrent package next to implement concurrency of the tool class (Reentrantreadwritelock, Semaphore, Countdownlatch, etc.), It is an exclusive lock like synchronized, and their two locks are compared as follows:1. The Reentrantlock implements the lock interface, providing the same mutex and visibility as the synchronized, as well as providing a reentrant nature.2. There

There are two lock classification methods.(1) from the perspective of the Database SystemThere are three types of locks:• Exclusive Lock)A resource with an exclusive lock can only be used by locked programs. Other operations on the resource are not accepted. SQL Server automatically uses an exclusive lock when executing the data UPDATE command, namely the INSERT,

The problem of exclusive or operation on bytes after phpmd5 is encrypted $ string = "! 22E2 ! ' 5aSJ ^ # $ 6 $ Md5 = md5 ("0e2c83d839c026a5e05303167feb90". md5 ($ string, true), true ); Performs an exclusive or operation on the 16-bit binary bytes returned after md5 encryption. $ Data = array (); $ Data [0] = "0 "; For ($ I = 0; $ I $ Data [$ I % 4 + 1] ^ = $ md5 [$ I]; } Then an integer is obtained. $ Va

The Internet has already solved the mouse exclusive problemArticleFor example, ogre + cegui + OIS perfectly solves the non-exclusive use of the mouse, and there is also an article on this basis to solve the no pointer problem of the mouse in the window border, for example, the ogre + cegui + OIS mouse is not exclusively used(Including code). These articles provide a complete solution to solve the mouse

Test the exclusive operation of PHPflock file locking. In php, most of the operations on files will use file locking to avoid conflict during simultaneous operations by multiple users, the following small series will test the exclusive file lock operation with everyone. some operations on files in php are most likely to use file lock to avoid conflict during simultaneous operations by multiple users, the fo

Php session file exclusive lock causes blocking problem solution ,. The PHP session file exclusive lock causes blocking. The Default session processor of PHP is session. save_handlerfiles (that is, the file ). If the same client concurrently sends multiple PHP session files with an exclusive lock, which causes blocking, The default session processor of PHP is se

Use an exclusive OR operator to encrypt integers.I. What is the operator: Binary ^ operators are predefined for integer and bool types. For an integer, ^ returns the bitwise XOR of the calculated operand ". For the bool operand, the logic of the ^ calculated operand is "exclusive or". That is to say, the result is true only when only one operand is true.Ii. Rules for XOR operation: If the corresponding bits

Java concurrent series of AbstractQueuedSynchronizer source code analysis (exclusive mode ), In the previous article "Java concurrency series [1] ---- brief analysis of AbstractQueuedSynchronizer source code analysis", we introduced some basic concepts of AbstractQueuedSynchronizer, mainly focusing on how AQS queues are implemented, what is the exclusive mode and shared mode, and how to understand the node

Nowadays, many malignant Viruses need to be scanned and killed using the exclusive killing tool, but some viruses will automatically prohibit the running of the exclusive killing tool. We often use other systems (such as DOS or PE) to scan and kill these stubborn viruses. Actually,Exclusive ToolIs a file that can delete viruses.Batch FileIt is not difficult to un

Label: style blog color ar use for strong SP data In this article, we will use the C language to implement the function of exchanging two variables of any type. It is difficult to use C for any type. If it is C ++, we can easily use the template function: template First, use ^ to exchange two integers. The code is simple but not easy to understand. a ^= b;b ^= a;a ^= b; Some people say that this writing method is amazing, but what I want to say is that the e
