/*! \brief
|
|
* Adapters acts as indirection layer, abstracting details of the record types (in the wrappers) from the higher levels
|
|
* of model. Please notice that nested adaptor uses helper classes for actually performing any actions. Different record
|
|
* types require different helpers (needs to be created in the subclass and then fetched via member function).
|
|
*
|
|
* Important point: don't forget to make sure that getData on the nestedColumn returns true (otherwise code will not
|
|
* treat the index pointing to the column as having children!
