The technical principles and practical application case analysis of the Circumflex Cache framework in the Java class library

Circumflex Cache (ring cache) is a powerful cache framework in the Java class library that provides a high -performance cache solution.This article will explore the technical principles of Circumflex Cache and its use in actual application cases. Technical principle: Circumflex Cache -based data structure based on a ring buffer is to use the ring buffer zone to achieve efficient cache data storage and access.This framework contains the following key concepts: 1. Circular buffer: The ring buffer is a fixed -size cycle array that can quickly access each element through array indexes.Data items are stored in a ring buffer in a certain order. When the buffer is full, the new data items will cover the oldest data items. 2. Key-value pair storage: Circumflex cache stores data through key-value pair.Each key corresponds to a unique cache item and is associated with a certain index in the ring buffer. 3. Cache strategy: Circumflex Cache supports multiple cache strategies, including the recent minimum use (LRU) strategy, advanced first -out (FIFO) strategy, and expiration time.These strategies are used to determine the storage position and elimination rules of the cache item. Actual application case: The following is a simple practical case, which shows the use of Circumflex Cache: import io.github.scrier2000.cache.CachedItem; import io.github.scrier2000.cache.CircularBufferCache; public class Main { public static void main(String[] args) { // Create a cache area of 10 CircularBufferCache cache = new CircularBufferCache(10); // Add cache items cache.put("key1", new CachedItem("value1")); cache.put("key2", new CachedItem("value2")); cache.put("key3", new CachedItem("value3")); // Get the value from the cache CachedItem item = cache.get("key1"); System.out.println (item.getValue ()); // Output: Value1 // Delete the cache item cache.delete("key2"); // All items in the output cache for (CachedItem c : cache.getAll()) { System.out.println(c.getValue()); } } } In this example, we created a cache area with a size of 10 and added three cache items to it.Get the value by key and delete specific cache items.Finally, we traverse the entire cache area and print all the cache values. Circumflex Cache provides a reliable and high -performance cache solution for Java developers through its efficient ring buffer data structure and flexible cache strategy.Whether it is web application or background service, Circumflex Cache can play a role in various scenarios to improve the performance and response speed of the application.
