Plus:
postLoad
This method is called during the export for setting the value to unmapped fields after entity is downloaded to datasource.

EXPORT:
       Entity- postLoad()
       staging - insert()
       Entity- postLoad() - depends on records

IMPORT:
       staging - postLoad()
       Entity - postLoad()
       Entity - initValue()
       Entity - validateField() - depends on no of fields
       Entity - validateWrite()
       Entity - insert() / update()
       Entity - persistEntity()
       Entity - initializeEntityDataSource()
       Entity - mapEntityToDataSource()
       Entity - insertEntityDataSource() / updateEntityDataSource()
       Entity - mapDataSourceToEntity()
       staging - postLoad()
