Interface Query<T>

All Superinterfaces:

Serializable

All Known Implementing Classes:

QueryAbstract, QueryDefault

public interface Query<T>
extends Serializable

For use by repository implementations, representing the values of a query.

The implementations of these objects are be provided by the underlying persistor/object store; consult its documentation.

Note: that not every object store will necessarily support this interface. In particular, the in-memory object store does not. For this, you can use the Filter interface to similar effect, for example in DomainObjectContainer.allMatches(Class, Filter)). Note that the filtering is done within the DomainObjectContainer rather than being pushed back to the object store.
