AbstractCriteriaQueryImpl (Batoo Persistence Core 2.0.0.0.RC2 API)

java.lang.Object
- org.batoo.jpa.core.impl.criteria.BaseQueryImpl<T>
- - org.batoo.jpa.core.impl.criteria.AbstractCriteriaQueryImpl<T>

Type Parameters:
T - the type of the result

All Implemented Interfaces:

javax.persistence.criteria.AbstractQuery<T>, BaseQuery<T>

Direct Known Subclasses:

CriteriaQueryImpl, SubQueryStub
```
public abstract class AbstractCriteriaQueryImpl<T>
extends BaseQueryImpl<T>
implements javax.persistence.criteria.AbstractQuery<T>
```
the definition of the functionality that is common to both top-level queries and subqueries.
It is not intended to be used directly in query construction.
All queries must have a set of root entities (which may in turn own joins).
All queries may have a conjunction of restrictions.

Since:

2.0.0
