Detailed introduction of key categories and methods in the JMemCached Core framework

JMEMCACHED is a high -performance, distributed memory object cache system developed based on Java language.The system uses a distributed architecture to run on multiple servers, and uses internal storage to provide fast data access and response.The core framework of JMEMCACHED contains multiple key classes and methods. The following will introduce some of them in detail. 1. MEMCACHEDSERVER class: The MEMCACHEDSERVER class is one of the core categories in the JMEMCACHED system. It is responsible for managing and processing requests for all clients.This class contains the following important methods: -START (): Start Memcachedserver and start the request of the client. -STOP (): Stop Memcachedserver and stop processing the client's request. -Accept (): Accept the client's connection request and create a corresponding connection processing thread. -PROCESSREQUEST (): The method of processing the client request, perform corresponding operations according to different types of operation types. 2. MEMCACHEDCONNECTION class: The MemcachedConnection class is a class used in the JMemCached system to handle client connection.Each client is connected to a MEMCACHEDCONNECTION object, which contains the following key methods: -Radrequest (): Read the request data from the client. -Parserequest (): Analyze the client request, and convert the request data into the operation type, key value and other parameters. -Sendresponse (): Send a response data to the client. 3. CacheStorage class: The CacheStorage class is a class used to store cache data in the JMEMCACHED system.It provides operations such as adding, deletion, modification and investigation of cache data.This class contains the following important methods: -get (): Obtain cache data according to the key value. -Set (): Set the cache data. -DELETE (): Delete the cache data of the specified key value. -Clear (): Clear all cache data. These classes and methods are part of the core framework of the JMEMCACHED, which can be expanded and customized in actual use.Below is a simple Java code example, showing how to use JMemCached to complete the basic cache operation: import com.jmemcached.CacheStorage; import com.jmemcached.MemcachedServer; public class JmemcachedExample { public static void main(String[] args) { // Create a cache storage object CacheStorage cacheStorage = new CacheStorage(); // Set the cache data cacheStorage.set("key1", "value1"); cacheStorage.set("key2", "value2"); // Get the cache data String value1 = cacheStorage.get("key1"); String value2 = cacheStorage.get("key2"); System.out.println("value1: " + value1); System.out.println("value2: " + value2); } } The above code creates a cache storage object and sets two cache data using the SET method.Then use the GET method to obtain these two cache data and print the output result.This is just a simple example. In actual use, you can also use more methods and functions according to needs to complete more complicated operations.
