How to integrate Arez Annotations framework in the Java class library
Arez is a Java framework for building response and observed applications.It provides a set of powerful annotations that help developers optimize the performance and maintenance of the application.This article will introduce how to integrate the Arez Annotations framework in your Java library.
### Step 1: Add Arez dependencies
First, you need to add the AREZ framework to your project dependence.You can achieve it by building tools such as Maven or Gradle.
For the Maven project, add the following code to the DependenCies section of your pom.xml file:
<dependency>
<groupId>org.realityforge.arez</groupId>
<artifactId>arez</artifactId>
<version>1.4.0</version>
</dependency>
For the Gradle project, add the following code in the DependenCies section of your Build.gradle file:
groovy
implementation 'org.realityforge.arez:arez:1.4.0'
When you build a project, the dependency will automatically analyze and download.
### Step 2: Use Arez Annotations
The Arez framework provides many useful annotations, you can use them in your Java class to optimize your application.
Here are some commonly used annotations and their functions:
-`@Arezcomponent`: Mark a class as Arez component so that it can benefit from Arez's automatic dependency tracking and status management.
-`@ACTION `: Mark a method as Arez action, use it with the Arez scheduler to ensure that the method is running on the correct time and thread.
-`@Autorun`: Mark a method as an automatic running method, and run automatically when the state changes in the component to handle related logic.
-`@Computed`: Mark a method as an AREZ calculation method to associate it with the dependent relationship to ensure that when the dependency item changes, the calculation method will automatically re -calculate.
-`@Ibserve`: Mark a method as an observator method. When the state of observation changes, the observer method will be automatically called.
The following is an example class that shows how to use AREZ annotation in the Java class library:
import arez.annotations.Action;
import arez.annotations.ArezComponent;
import arez.annotations.Computed;
import arez.annotations.Observe;
@ArezComponent
public class MyComponent {
private String data;
@Action
public void setData(String newData) {
data = newData;
}
@Computed
public String getDerivedData() {
return "Derived " + data;
}
@Observe
public void onDataUpdated() {
System.out.println("Data updated: " + data);
}
}
In this example, we used the@Arezcomponent` to mark the `mycomponent` class as an Arez component.We also used the `@action` to mark the` setdata` method as the AREZ action, the `@computed` method` getDerivedAta "as the AREZ calculation method, and use the@observe` widataUpdated` method as the Arez observer method.
### in conclusion
After integrated Arez Annotation's framework, you can use the annotations provided to optimize your Java library.AREZ's automatic dependency tracking and status management will help you build response, observed applications.
I hope this article will help you integrated Arez Annotations framework!
