Class DaoGetDependentQuery<I extends Serializable,P extends Storable<I> & Dependable<E>,T extends Transportable<? super T,I> & Dependent<R>,Q extends Transportable<? super Q,I> & Dependent<E>,E extends Serializable,R extends Transportable<? super R,E>>

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

com.hp.util.dao.query.DaoGetDependentQuery<I,P,T,Q,E,R>

Type Parameters:

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

P - type of the persistent object.

T - type of the transport object

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

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.

R - type of the owner transport object

extends ReadQuery<Q>

Creates a query.

This method is a convenience to infer the generic types.

Parameters:

id - transport object's id.

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

Returns:

a query to add a transport object.

execute

protected Q execute(DataStoreContext context)

Description copied from class: ReadQuery

Executes the query.

Specified by:

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

Parameters:

context - data store context.

Returns:

the result of the query.
