Interface BaseDao<I extends Serializable,P extends Storable<I>,T extends Transportable<? super T,I>,F,S>

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 model persistent object

T - type of the transport object

F - type of the associated filter

S - type of the associated sort specification type

All Known Subinterfaces:

Method Detail

get

P get(Id<T,I> id,
    DataStoreContext context)

Get the persistent object with the given id.

Parameters:

id - persistent object's id
