Modifier and Type	Method	Description
K	create(K1 keyComponent1, K2 keyComponent2, T entity)	Create an entity using a specific first key component, assuming the second component is generated by the database.
Collection<T>	findAll(K1 keyComponent1, K2 keyComponent2, List<net.solarnetwork.domain.SortDescriptor> sorts)	Find all persisted entities available matching the first key component, optionally sorted in some way.
default Collection<T>	findAllForKey(K filter, List<net.solarnetwork.domain.SortDescriptor> sorts)	Find all persisted entities available matching the components of a composite key, optionally sorted in some way.

Method Details

create

K create(K1 keyComponent1,
 K2 keyComponent2,
 T entity)

Create an entity using a specific first key component, assuming the second component is generated by the database.

Parameters:

keyComponent1 - the assigned first key component

keyComponent2 - the assigned second key component

entity - the domain object so store; the Identity.getId() of the entity will be ignored

Returns:

the primary key of the stored object

findAll

Collection<T> findAll(K1 keyComponent1,
 K2 keyComponent2,
 List<net.solarnetwork.domain.SortDescriptor> sorts)

Find all persisted entities available matching the first key component, optionally sorted in some way.

The sortDescriptors parameter can be null, in which case the sort order is not defined and implementation specific.

Parameters:

keyComponent1 - the first key component to restrict the results to

keyComponent2 - the second key component to restrict the results to

sorts - list of sort descriptors to sort the results by

Returns:

list of all persisted entities, or empty list if none available

findAllForKey

default Collection<T> findAllForKey(K filter,
 List<net.solarnetwork.domain.SortDescriptor> sorts)

Description copied from interface: GenericCompositeKeyFilterableDao

Find all persisted entities available matching the components of a composite key, optionally sorted in some way.

Only key components that are assigned are used to filter the result. The sortDescriptors parameter can be null, in which case the sort order is not defined and implementation specific.

Specified by:

findAllForKey in interface GenericCompositeKeyFilterableDao<T extends net.solarnetwork.dao.Entity<K>,K extends CompositeKey3<K1,K2,K3>>

Parameters:

filter - the key that acts like a filter to restrict the results to

sorts - list of sort descriptors to sort the results by

Returns:

list of all persisted entities, or empty list if none available
