EzyFox Binding Introduction

EzyFox Binding is a library for marshal POJO to EzyObject or EzyArray and unmarshal EzyObject and EzyArray to POJO.

1. Structure of EzyFox Binding

  1. EzyBindingContext: a composite object, it creates EzyMashaller and EzyUnmashaller object
  2. EzyMashaller: a composite object, it manages EzyWriter objects
  3. EzyUnmashaller: a composite object, it manages EzyReader objects
  4. EzyWriter: convert a POJO to EzyArray or EzyObject
  5. EzyReader: convert a EzyArray or EzyObject to POJO
EzyFox Binding also has many annotations and you can find out theme here.

2. Install EzyFox Binding

You can add to your dependency like this: 
<dependency>
    <groupId>com.tvd12</groupId>
    <artifactId>ezyfox-binding</artifactId>
    <version>1.2.7</version>
</dependency>
The latest version can be found in the Maven Central repository.

3. Create a EzyBindingContext

To create a EzyBindingContext you just need provide packages and EzyFox Binding will scan and create EzyReader, EzyWriter for which classes that's annotated by @EzyArrayBinding or @EzyObjectBinding annotations, example: 
 final EzyBindingContext bindingContext = EzyBindingContext.builder()
    .scan("com.tvd12.ezyfox.example.binding")
    .build();

4. Marshal an POJO

To marshal a POJO you need create a EzyMarshaller instance first, please remember you just need create only one EzyMarshaller instance. And then use marshal function to do. For which class's annotated with @EzyArrayBinding, it will be marshalled to EzyArray. For which class's annotated with @EzyObjectBinding, it will be marshalled to EzyObject, example: 
package com.tvd12.ezyfox.example.binding.data;

import com.tvd12.ezyfox.binding.annotation.EzyArrayBinding;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@EzyArrayBinding
@AllArgsConstructor
@NoArgsConstructor
public class Author {
    private long id;
    private String name;
}

package com.tvd12.ezyfox.example.binding.data;

import com.tvd12.ezyfox.binding.annotation.EzyObjectBinding;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@EzyObjectBinding
@AllArgsConstructor
@NoArgsConstructor
public class Book {

    private long id;
    private String name;
    private long authorId;
}

final EzyMarshaller marshaller = bindingContext.newMarshaller();

final EzyObject bookMap = marshaller
    .marshal(new Book(1, "EzyFox in Action", 1));
System.out.println("bookMap: " + bookMap);

final EzyArray authorArray = marshaller
    .marshal(new Author(1, "Young Monkeys"));
System.out.println("authorArray: " + authorArray);

5. Unmarshal a value

To unmarshal a value to POJO you need create a EzyUnmarshaller instance first, please remember you just need create only one EzyUnmarshaller instance. And then use unmarshal function to do. For which class's annotated with @EzyArrayBinding, it will be unmarshalled form a EzyArray. For which class's annotated with @EzyObjectBinding, it will be unmarshalled form a EzyObject, example: 
final EzyUnmarshaller unmarshaller = bindingContext.newUnmarshaller();

final Book book = unmarshaller.unmarshal(bookMap, Book.class);
System.out.println("book: " + book);

final Author author = unmarshaller.unmarshal(authorArray, Author.class);
System.out.println("author: " + author);
