Examples of ma.glasnost.orika.MapperFacade

ma.glasnost.orika.MapperFacade
The main runtime interface between a Java application and Orika. This is the central interface abstracting the service of a Java bean mapping.

The main operation of MapperFacade is map() that copy from a deeply structured one object to an other.

MapperFacade manages the state of a mapping operation through MappingContext.
The operation of mapping may include :
- Creation of new objects : newObject()
- Conversion object to another type: convert()
- Mapping recursively an object to an other class : map()
Example of code to map an instance of Entity(entity ) to DTO class:
```
 ... DTO newDTO = mapperFacade.map(entity, DTO.class); ... 
```
