Explore FLUENT Reflection framework technical principles in the Java class library
Introduction: Fluent Reflection is a framework for reflection in Java. It provides a more convenient and elegant way to use reflex technology.This article will explore the principle of the FLUENT Reflection framework and its application in the Java library.
1. What is Fluent Reflection?
FLUENT Reflection is an open source framework. It provides a more intuitive and convenient programming method by simplifying the use of Java reflection, enabling developers to be easier to use and operate the reflection function in the Java library.
2. The principle of Fluent Reflection
The core idea of Fluent Reflection is to simplify the calling link of the Java reflection, making it easier to understand and use.It connects multiple reflex operations by using a stream API and method chain to form a more intuitive and coherent code structure.
Specifically, Fluent Reflection mainly relies on the following two principles to achieve:
1. Builder mode: FLUENT Reflection uses the builder mode to create a reflective operation chain.When creating an operation chain, developers can gradually add reflection operations according to their own needs through chain calls, and finally build a complete operation chain.
2. Method Chain: Fluent Reflection connects multiple reflex operations by method chain.When performing reflection operations, developers only need to continuously call the reflex method that needs to be executed, instead of re -obtain reflex objects or classes after each reflection operation.This makes the code more concise and coherent.
Three, FLUENT Reflection application example
The following is a simple sample code using Fluent Reflection:
// Create a POJO object with a GET and SET method
public class Person {
private String name;
private int age;
public Person() {}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
// Use FLUENT Reflection Set and Get Object Properties Value
public class Main {
public static void main(String[] args) {
// Create a Person object
Person person = new Person();
// Use FLUENT Reflection to set the object attribute value
Reflect.on(person).set("name", "Alice").set("age", 25);
// Use FLUENT Reflection to obtain object attribute values
String name = Reflect.on(person).get("name");
int age = Reflect.on(person).get("age");
// Print attribute value
System.out.println("Name: " + name);
System.out.println("Age: " + age);
}
}
In the above example, we set and obtain the attributes of the Person object through the FLUENT Reflection framework.Create an operating chain by using the Reflect.on () method, and then set and obtain the attribute value by set () and get () methods.Using Fluent Reflection can make the code more concise and easy to understand.
Conclusion:
The application of the FLUENT Reflection framework in the Java library makes the use of reflection more convenient and elegant.By using its simplified calling links and method chains, developers can more conveniently use and operate the reflection function in the Java library.It is hoped that the exploration of this article will help readers understand the principles and applications of the Fluent Reflection framework.
