Activeio :: Core's key features

Activeio is a Java library that provides a highly scalable and high throughput network programming model.The core of Activeio has several key features that make it an ideal choice for developing high -performance network applications. 1. Asynchronous non-blocking IO (Non-Blocking IO): Activeio uses asynchronous non-blocking IO models to process network communication, which means that applications can perform other tasks while waiting for IO operations without having to block threads.In this way, system resources can be made to improve the throughput and response performance of the application. The following is an example of using Activeio for asynchronous non -blocking IO Java code: Connection connection = new Connection(); // Set the data receiving recovery function connection.setReceiver(new Receiver() { @Override public void received(Connection connection, Object data) { // Process the received data System.out.println("Received data: " + data); } }); // Start the connection connection.start(); // send data connection.send("Hello, ActiveIO!"); // The program continues to perform other tasks // Turn off the connection connection.close(); In the above example, the `Connection` class represents the connection with the remote server.By setting the receiving recovery function, the application can process the received data when the data arrives.`Connection.send` method is used to send data.After sending data, the application can continue to perform other tasks without waiting for IO operation to complete. 2. Multiplexing: Activeio uses the multi -way reuse mechanism to manage multiple concurrent connections in one IO thread.This method uses less thread resources to process a large number of concurrent connections, thereby reducing the expenses of thread management.This is particularly beneficial for high -load network applications and can improve the scalability and performance of the application. The following are examples of Java code for multi -way reuse using Activeio: Selector selector = Selector.open(); // Register to connect to the selector connection.register(selector, SelectionKey.OP_READ); while (true) { // Select the prepared IO operation selector.select(); // Processing events on the selector for (SelectionKey key : selector.selectedKeys()) { if (key.isReadable()) { // Treatment of reading events Connection connection = (Connection) key.attachment(); Object data = connection.read(); System.out.println("Received data: " + data); } } // Clear events on the selector selector.selectedKeys().clear(); } In the above example, the connection is registered to the selector by calling the `Connection.register` method, and specify the IO operation type that is interested in.Subsequently, the prepared IO operation is continuously selected through the cycle, and then used the corresponding code processing event, such as reading data. 3. Supported transmission protocols and codecs: Activeio provides support for a variety of transmission protocols, and has built -in some commonly used codecs to enable developers to easily process data under different protocols.These codecs can be used to decode the data from the byte flow to the Java object and encode the Java object into byte flow in order to transmit it on the network.This greatly simplifies the processing and analysis of network data. In summary, the core features of Activeio include asynchronous non -blocking IO, multi -way reuse and support for transmission protocols.By using these characteristics, developers can build high -performance, scalable network applications.
