Class DaoFindDependentQuery<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<List<Q>>

com.hp.util.dao.query.DaoFindDependentQuery<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.

public class DaoFindDependentQuery<P extends Storable<?> & Dependable<E>,Q extends Transportable<? super Q,?> & Dependent<E>,F,S,E extends Serializable>
extends ReadQuery<List<Q>>

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

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

Returns:

a query to add a transport object

execute

protected List<Q> execute(DataStoreContext context)

Description copied from class: ReadQuery

Executes the query.

Specified by:

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

Parameters:

context - data store context.

Returns:

the result of the query.
