JMapper Framework

Fast as hand-written code with zero compromise.

Artifact information

Status

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

Most relevant features:

• One to Many and Many to One relationship
• dynamic conversions, whose body adapts to every relationship
• inherited configurations, 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

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

<jmapper>
  <class name="it.jmapper.bean.Destination">
    <attribute name="id">
      <value name="id"/>
    </attribute>
    <attribute name="destinationField">
      <value name="sourceField">
    </attribute>
  </class>
</jmapper>

API

JMapperAPI jmapperAPI = new JMapperAPI()
    .add(mappedClass(Destination.class)
             .add(attribute("id")
                     .value("id"))
             .add(attribute("destinationField")
                     .value("sourceField")));

Creation

JMapper<Destination, Source> mapper;

Annotation

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

XML

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

API

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

Usage

Source source = new Source("id", "sourceField", "other");
Destination destination = mapper.getDestination(source);

Result

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

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