create

public Content create(Content content)

Description copied from interface: ContentDao

Creates an instance of com.communote.server.persistence.resource.Content and adds it to the persistent store.

create

public Object create(int transform,
                     Content content)

Description copied from interface: ContentDao

Does the same thing as ContentDao.create(com.communote.server.model.note.Content) 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.
