Method Detail

create

Content create(Content content)

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

create

Object create(int transform,
              Content content)

Does the same thing as 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.

create

Collection<?> create(int transform,
                     Collection<Content> entities)

Does the same thing as 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 entities (into value objects for example). By default, transformation does not occur.

create

Collection<Content> create(Collection<Content> entities)

Creates a new instance of com.communote.server.persistence.resource.Content and adds from the passed in entities collection

Parameters:

entities - the collection of com.communote.server.persistence.resource.Content instances to create.

Returns:

the created instances.

evict

void evict(Content entity)

Evicts (removes) the entity from the hibernate cache

Parameters:

entity - the entity to evict

load

Object load(int transform,
            Long id)

Does the same thing as load(Long) 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 in this class 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.

Parameters:

id - the identifier of the entity to load.

Returns:

either the entity or the object transformed from the entity.

load

Content load(Long id)

Loads an instance of com.communote.server.persistence.resource.Content from the persistent store.

loadAll

Collection<Content> loadAll()

Loads all entities of type Content.

Returns:

the loaded entities.

loadAll

Collection<?> loadAll(int transform)

Does the same thing as loadAll() 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.

Parameters:

transform - the flag indicating what transformation to use.

Returns:

the loaded entities.

remove

void remove(Content content)

Removes the instance of com.communote.server.persistence.resource.Content from the persistent store.

remove

void remove(Collection<Content> entities)

Removes all entities in the given entities collection.

remove

void remove(Long id)

Removes the instance of com.communote.server.persistence.resource.Content having the given identifier from the persistent store.
