Java class library based on the "Activity Compose" framework
Java class library based on the "Activity Compose" framework
In the Java library, using the "Activity Compose" framework can be more convenient to programming.This article will introduce how to use this framework and related programming code and configuration.
I. Overview
"Activity Compose" is a Java -based open source framework, which aims to simplify the complexity of concurrent programming and provide a very intuitive and easy -to -use way to handle concurrent tasks.It provides a set of powerful categories and methods that can help developers avoid common concurrent problems, such as competitive conditions and deadlocks.
2. Installation and configuration
1. Download the JAR package of the "Activity Compose" framework and add it to your project dependence.
2. In your Java class, import the "Activity Compose" related class and methods.
import activitycompose.Activity;
import activitycompose.ActivityContext;
import activitycompose.ActivityGroup;
import activitycompose.Template;
3. Parallel programming foundation
1. Create an Activity
Activity is the basic unit of concurrent programming, which represents a task that can be performed independently.
Activity<String> activity = Activity.of(() -> {
// Executive logic of parallel task
Return "task execution result";
});
2. Combine multiple Activity
Activity can be combined through ActivityGroup to form some concurrent task groups.
ActivityGroup<String> group = ActivityGroup.of(activity1, activity2, activity3);
3. Execute Activity
You can execute an Activity by calling the "Execute" method of Activity, which will return a FUTURE object.
Future<String> future = activity.execute();
4. Asynchronous processing concurrent results
Use the Future object to process the results of the concurrent task asynchronously.After the task is completed, the result can be obtained through the Future's "get" method.
String result = future.get();
5. Example: Calculate the results of the concurrent task
The following examples will show how to calculate the results of the concurrent task using the "Activity Compose" framework.
import activitycompose.*;
public class Example {
public static void main(String[] args) throws Exception {
// Create a concurrent task
Activity<Integer> activity1 = Activity.of(() -> {
Thread.sleep(2000);
return 1;
});
Activity<Integer> activity2 = Activity.of(() -> {
Thread.sleep(3000);
return 2;
});
Activity<Integer> activity3 = Activity.of(() -> {
Thread.sleep(1000);
return 3;
});
// Combination and send tasks
ActivityGroup<Integer> group = ActivityGroup.of(activity1, activity2, activity3);
// concurrent execution task group
Future<Integer> future = group.execute();
// asynchronous processing results
future.thenAccept(result -> {
System.out.println ("concurrent task results:" + result);
});
// Waiting for the result output
Thread.sleep(4000);
}
}
In the above examples, we have created three concurrent tasks to simulate different execution time.By combining these tasks into a task group, perform concurrencing, and finally handle the results of the task.The console will output the results of the mission.
Summarize:
By using the "Activity Compose" framework, we can more conveniently perform concurrent programming to avoid some common concurrency problems.You can create Activity and ActivityGroup, and use the Execute method to perform the task concurrently, and finally handle the results of the task asynchronous.This can greatly improve the efficiency and reliability of concurrent programming.
