Class DaoPagedFindDependentQuery<P extends Storable<?> & Dependable<E>,Q extends Transportable<? super Q,?> & Dependent<E>,F,S,E extends Serializable>

java.lang.Object

com.hp.util.dao.ReadQuery<Page<Q>>

com.hp.util.dao.query.DaoPagedFindDependentQuery<P,Q,F,S,E>

Type Parameters:

P - type of the persistent object.

Q - type of the transport object with a reference to the owner's id.

F - type of the associated filter.

S - type of the associated sort specification type.

E - type of the owner persistent object and owner transport object id. This type should be immutable. It is critical this type implements equals() and hashCode() correctly.

Creates a query.

This method is a convenience to infer the generic types.

Parameters:

filter - filter used to select the transport objects.

sortSpecification - sort specification.

pageRequest - page request.

dao - DAO used to perform the database operations for the query.

Returns:

a query to add a transport object.

execute

protected Page<Q> execute(DataStoreContext context)

Description copied from class: ReadQuery

Executes the query.

Specified by:

execute in class ReadQuery<Page<Q extends Transportable<? super Q,?> & Dependent<E>>>

Parameters:

context - data store context.

Returns:

the result of the query.
