try to provide multi ways to help you marshal and unmarshal data easily.

1. By default

When you provide packages, EzyFox Binding will scan the packages and create reader/writer for which classes that be annotated by EzyArrayBinding and EzyObjectBinding. Example we have 3 classes like this:

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 Author author;
    private Category category;
}

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 Category {
    private long id;
    private String name;
}

And then we create a EzyBindingContext like this:

final EzyBindingContext bindingContext = EzyBindingContext.builder()
    .scan("com.tvd12.ezyfox.example.binding")
    .build();

EzyFox Binding will scan the package and create readers/writers for the 3 classes. And then we can marshal and unmarshal the classes without any additional configurations.

final EzyMarshaller marshaller = bindingContext.newMarshaller();
final EzyUnmarshaller unmarshaller = bindingContext.newUnmarshaller();
final EzyObject bookMap = marshaller
    .marshal(
        new Book(
            1,
            "EzyFox in Action",
            new Author(1, "Young Monkeys"),
            new Category(1, "Technical")
        )
    );
System.out.println("bookMap: " + bookMap);
final Book book = unmarshaller.unmarshal(bookMap, Book.class);
System.out.println("book: " + book);

2. Custom Reader / Writer

Sometimes, for some reason, you need to create a customization reader / writer for your data class, Ezyfox Binding will provide to you 3 ways

2.1 Implements EzyTemplate

EzyTemplate

, example:

package com.tvd12.ezyfox.example.binding.converter;
import com.tvd12.ezyfox.binding.EzyMarshaller;
import com.tvd12.ezyfox.binding.EzyTemplate;
import com.tvd12.ezyfox.binding.EzyUnmarshaller;
import com.tvd12.ezyfox.binding.annotation.EzyTemplateImpl;
import com.tvd12.ezyfox.entity.EzyArray;
import com.tvd12.ezyfox.example.binding.data.Author;
import com.tvd12.ezyfox.factory.EzyEntityFactory;
@EzyTemplateImpl
public class AuthorConverter
    implements EzyTemplate<EzyArray, Author> {
    @Override
    public Author read(
        EzyUnmarshaller unmarshaller,
        EzyArray array
    ) {
        return new Author(
            array.get(0, long.class),
            array.get(1, String.class)
        );
    }
    @Override
    public EzyArray write(EzyMarshaller marshaller, Author author) {
        return EzyEntityFactory.newArrayBuilder()
            .append(author.getId())
            .append(author.getName())
            .build();
    }
}

2.2 Implements EzyReader

EzyReader

, example:

package com.tvd12.ezyfox.example.binding.converter;
import com.tvd12.ezyfox.binding.EzyReader;
import com.tvd12.ezyfox.binding.EzyUnmarshaller;
import com.tvd12.ezyfox.binding.annotation.EzyReaderImpl;
import com.tvd12.ezyfox.entity.EzyArray;
import com.tvd12.ezyfox.example.binding.data.Author;
@EzyReaderImpl
public class AuthorReader implements EzyReader<EzyArray, Author> {
    @Override
    public Author read(EzyUnmarshaller unmarshaller, EzyArray array) {
        return new Author(
            array.get(0, long.class),
            array.get(1, String.class)
        );
    }
}

2.3 Implements EzyWriter

EzyWriter

, example:

package com.tvd12.ezyfox.example.binding.converter;
import com.tvd12.ezyfox.binding.EzyMarshaller;
import com.tvd12.ezyfox.binding.EzyWriter;
import com.tvd12.ezyfox.binding.annotation.EzyWriterImpl;
import com.tvd12.ezyfox.entity.EzyArray;
import com.tvd12.ezyfox.example.binding.data.Author;
import com.tvd12.ezyfox.factory.EzyEntityFactory;
@EzyWriterImpl
public class AuthorWriter implements EzyWriter<Author, EzyArray> {
    @Override
    public EzyArray write(EzyMarshaller marshaller, Author author) {
        return EzyEntityFactory.newArrayBuilder()
            .append(author.getId())
            .append(author.getName())
            .build();
    }
}

3. Specific Reader / Writer

In some cases, when your data is complicated and you want to specific reader / writer on a field, you can do like this:

package com.tvd12.ezyfox.example.binding.data;
import com.tvd12.ezyfox.binding.annotation.EzyObjectBinding;
import com.tvd12.ezyfox.binding.annotation.EzyReader;
import com.tvd12.ezyfox.binding.annotation.EzyWriter;
import com.tvd12.ezyfox.example.binding.converter.AuthorReader;
import com.tvd12.ezyfox.example.binding.converter.AuthorWriter;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@EzyObjectBinding
@AllArgsConstructor
@NoArgsConstructor
public class Book {
    private long id;
    private String name;
    @EzyReader(AuthorReader.class)
    @EzyWriter(AuthorWriter.class)
    private Author author;
    private Category category;
}
