Method Detail

create

public Object create(int transform,
                     Note note)

Does the same thing as NoteDao.create(Note) with an additional flag called transform. If this flag is set to TRANSFORM_NONE then the returned entity will NOT be transformed. If this flag is any of the other constants defined here then the result WILL BE passed through an operation which can optionally transform the entity (into a value object for example). By default, transformation does not occur.

Specified by:

create in interface NoteDao

Overrides:

create in class NoteDaoBase

See Also:

NoteDao.create(int transform, Note)

forceLoad

public Note forceLoad(Long id)

Load a note from the persistent store, even if it is cached. In case the note was cached the updated note will be put into the cache. Note: when called from within a session where the entity is already loaded, the returned object will be the one previously loaded into the session. However, a normal load from a later session will return the latest from the persistent storage.

Parameters:

id - the ID of the note to load

Returns:

the loaded note or null if there is no note with the given ID
