Kevoree :: API framework in multi -threaded programming
Kevoree is an open source framework for multi -threaded programming. It provides a simple and flexible way to manage the execution and communication of multiple threads.In this article, we will introduce the use of the API framework of Kevoree and provide some Java code examples.
1. Introduce Kevoree dependencies
First, we need to introduce related dependence of Kevoree in the project.It can be implemented by adding the following code to the `pom.xml` file:
<dependencies>
<dependency>
<groupId>org.kevoree</groupId>
<artifactId>org.kevoree.api</artifactId>
<version>5.4.1</version>
</dependency>
</dependencies>
2. Create Kevoree container
Using the Kevoree framework, we can create a container containing multiple components.Each component runs in its own thread and can communicate through message transmission.Below is a sample code for creating a Kevoree container:
import org.kevoree.api.KevoreeFactory;
import org.kevoree.api.ModelService;
import org.kevoree.api.PrimitiveCommand;
import org.kevoree.api.handler.ModelListener;
import org.kevoree.api.handler.ModelListenerAdapter;
public class KevoreeContainerExample {
public static void main(String[] args) {
// Create a Kevoree container
KevoreeFactory factory = new MyKevoreeFactory();
ModelService modelService = factory.createModelService();
// Add a model monitor
ModelListener listener = new ModelListenerAdapter() {
@Override
public void modelUpdated() {
// The logical processing of the model update
}
};
modelService.registerModelListener(listener);
// Start Kevoree container
PrimitiveCommand startCommand = modelService.createStartCommand();
modelService.submitCommand(startCommand);
}
// Custom implementation of CEVoreeFactory
public static class MyKevoreeFactory extends KevoreeFactory {
// Implement the relevant method
}
}
3. Create Kevoree components
Using the Kevoree framework, we can create multiple components and define the dependency relationship between them.Each component can achieve its own logic and communicate with other components.Below is an example code that creates a Kevoree component:
import org.kevoree.annotation.ComponentType;
import org.kevoree.annotation.Input;
import org.kevoree.annotation.Output;
import org.kevoree.annotation.Param;
@ComponentType
public class MyKevoreeComponent {
@Param(defaultValue = "Hello Kevoree!")
private String message;
@Input
public void inputMethod(Object msg) {
System.out.println("Received message: " + msg);
}
@Output
public Object outputMethod() {
return message;
}
}
In the above example, we created a component called `mykevorecomponent`.This component contains an input method `inputMethod` and an output method` OutputMethod`, which are used to receive and send messages, respectively.`@Input` and`@output` Annotations are used to mark the input and output method.
4. Run Kevoree container
After completing the creation of the Kevoree container and components, we can run the KEVoree container and let the components communicate.The following is a simple sample code:
import org.kevoree.api.KevoreeFactory;
import org.kevoree.api.ModelService;
import org.kevoree.api.PrimitiveCommand;
import org.kevoree.api.handler.ModelListener;
import org.kevoree.api.handler.ModelListenerAdapter;
public class KevoreeContainerExample {
public static void main(String[] args) {
// Create a Kevoree container
KevoreeFactory factory = new MyKevoreeFactory();
ModelService modelService = factory.createModelService();
// Add a model monitor
ModelListener listener = new ModelListenerAdapter() {
@Override
public void modelUpdated() {
// The logical processing of the model update
}
};
modelService.registerModelListener(listener);
// Start Kevoree container
PrimitiveCommand startCommand = modelService.createStartCommand();
modelService.submitCommand(startCommand);
// Send messages between components
Object message = "Hello from component!";
modelService.send("myComponent", "inputMethod", message);
}
// Custom implementation of CEVoreeFactory
public static class MyKevoreeFactory extends KevoreeFactory {
// Implement the relevant method
}
}
In the above example, we created a component called `mykevorecomponent`, and used the` ModelService.send` method to send a message to the `InputMethod` method of the component.
Through these examples, we can understand how to use the Kevoree API framework for multi -threaded programming.Hope this article will help you!
