Activeio :: core framework Introduction

Activeio is a Java asynchronous I/O framework that focuses on providing high -performance and scalable network programming solutions.The Activeio framework is built on the basis of Java NIO (New I/O). Through its core component, a powerful and flexible asynchronous network operation API provides. The core component of Activeio is Activity.Each activity represents a network operation, such as reading, writing, connecting, accepting.Activities can be independent or as sub -activities of other activities, so as to form a hierarchical structure of the activity.Through the hierarchical structure of the activity, Activeio can handle complex asynchronous network operations. The Activeio also provides an ActivityListener interface for applications to monitor and respond to event -related events.These events include the beginning of the event, the completion of the activity, the errors in the event, etc.By achieving an active listener interface, the application can take customized actions when needed. Below is a sample code using the Activeio framework: import org.activeio.ActiveIO; import org.activeio.listener.ActivityAdapter; import org.activeio.net.AIOReadActivity; import org.activeio.net.AIOWriteActivity; import java.nio.ByteBuffer; import java.nio.channels.AsynchronousSocketChannel; public class ActiveIOExample { public static void main(String[] args) { try { // Create asynchronous socket channel AsynchronousSocketChannel channel = AsynchronousSocketChannel.open(); // Connect to the server channel.connect(serverAddress, null, new CompletionHandler<Void, Void>() { @Override public void completed(Void result, Void attachment) { // connection succeeded // Create reading activities AIOReadActivity readActivity = new AIOReadActivity(channel); // Add reading activity listener readActivity.addActivityListener(new ActivityAdapter() { @Override public void activityCompleted(Activity activity) { // Read the activity to complete ByteBuffer buffer = readActivity.getReadBuffer(); String message = new String(buffer.array(), buffer.position(), buffer.limit()); System.out.println("Received message: " + message); } @Override public void activityFailed(Activity activity, Throwable exception) { // Reading activities Fail exception.printStackTrace(); } }); // Create writing activities AIOWriteActivity writeActivity = new AIOWriteActivity(channel); // Add writing to the event listener writeActivity.addActivityListener(new ActivityAdapter() { @Override public void activityCompleted(Activity activity) { // Write the activity to complete System.out.println("Message sent successfully!"); } @Override public void activityFailed(Activity activity, Throwable exception) { // Failure to write the event exception.printStackTrace(); } }); // Start reading data readActivity.start(); // Send data to the server ByteBuffer buffer = ByteBuffer.wrap("Hello, server!".getBytes()); writeActivity.setWriteBuffer(buffer); writeActivity.start(); } @Override public void failed(Throwable exc, Void attachment) { // Connection failed exc.printStackTrace(); } }); // Start the Activeio framework ActiveIO.start(); } catch (IOException e) { e.printStackTrace(); } } } The above example demonstrates the basic steps of using the Activeio framework for asynchronous network programming.First, create an asynchronous socket channel and connect to the server.Then create reading and writing activities, and add corresponding activity listeners.Finally, start reading and writing activities.When successful or failure, the corresponding activity listener method will be called separately.In this way, you can easily handle asynchronous network operations and perform custom operations as needed.
