Method Detail

getIdsFromName

List<String> getIdsFromName(String name)
Returns the list of ids of T objects that have the given name. Names may be unique but often are not, hence the List return type.

Parameters:
name - the name of the T.
Returns:
all IDs of objects matching the name or the empty list on name lookup failure.

nameExists

boolean nameExists(String name)
Returns true if the name would resolve to a domain object.

Parameters:
name - the addressable name.
Returns:
true only if the name resolves to a domain object in the database.

idExists

boolean idExists(Long id)
Returns true if the id would resolve to a domain object.

Parameters:
id - the primary key.
Returns:
true only if the id resolves to a domain object in the database.

get

T get(Long id)
Get by id.

Parameters:
id - the id.
Returns:
the domain object or null on lookup failure.

getAll

@NotNull
Collection<T> getAll()
Gets all domain objects of this type in the underlying database. Note that calling this may not be a good idea for some domain object types.

Returns:
all objects of the configured type in the database (possibly empty, never null).
