Specified by:

mapToObjectFromFullMap in interface MiddleComponentMapper

Parameters:

entityInstantiator - An entity instatiator bound with an open versions reader.

data - Full object data.

dataObject - An optional object representation of the data.

revision - Revision at which the data is read.

Returns:

An object with data corresponding to the one found in the given map.

                               Object obj)

Description copied from interface: MiddleComponentMapper

Maps from an object to the object's map representation (for an entity - only its id).

Specified by:

mapToMapFromObject in interface MiddleComponentMapper

Parameters:

data - Map to which data should be added.
