##### Write the configuration using what you prefer: Annotation, XML or API.

Most relevant features:

  * [One to Many](https://github.com/jmapper-framework/jmapper-core/wiki/One-To-Many) and [Many to One](https://github.com/jmapper-framework/jmapper-core/wiki/Many-To-One) relationship

  * [dynamic conversions](https://github.com/jmapper-framework/jmapper-core/wiki/Conversion-examples), whose body adapts to every relationship

  * [inherited configurations](https://github.com/jmapper-framework/jmapper-core/wiki/Inheritance-examples), you can split the configuration along the hierarchy

  * and more..

   

  

**especially its use is intuitive**

## Configuration

Below it is shown the same configuration in the three types allowed

##### Annotation

```java

class Destination{                      class Source{

    @JMap

    private String id;                      private String id;

    @JMap("sourceField")                    

    private String destinationField;        private String sourceField;

    private String other;                   private String other;

    // getters and setters...               // getters and setters...

}                                       }

```

##### XML

```xml

  

    

      

    

    

      

    

  

```

##### API

```java

JMapperAPI jmapperAPI = new JMapperAPI()

    .add(mappedClass(Destination.class)

             .add(attribute("id")

                     .value("id"))

             .add(attribute("destinationField")

                     .value("sourceField")));

```

## Creation

```java

JMapper mapper;

```

##### Annotation

```java

mapper = new JMapper<>(Destination.class, Source.class);

```

##### XML

```java

mapper = new JMapper<>(Destination.class, Source.class, xml);

```

##### API

```java

mapper = new JMapper<>(Destination.class, Source.class, jmapperAPI);

```

## Usage

```java

Source source = new Source("id", "sourceField", "other");

Destination destination = mapper.getDestination(source);

```

## Result

```java

destination ["id", "sourceField", null]

```

*With JMapper we have all the advantages of dynamic mapping with the performance of static code, with 0 memory consumption.*
