Parameters:

dtoClass - the DTO class.

Method Detail

getDtoClass

public Class<D> getDtoClass()

Description copied from interface: Assembler

Returns the DTO type handled by the assembler.

This method is used by Assembler.assembleDtoFromAggregate(Object) to determine the DTO type to instantiate.

Specified by:

getDtoClass in interface Assembler<A,D>

Returns:

the DTO class this assembler handles.

newDto

protected D newDto()

This protected method is in charge of creating a new instance of the DTO.

The actual implementation is fine for simple POJO, but it can be extended. The developers will then use getDtoClass() to retrieve the destination class.

Returns:

the DTO instance.
