extends com.holonplatform.core.query.QueryBuilder<JpaQuery<T>>, com.querydsl.jpa.JPQLQuery<T>
    QueryDSL JPA query interface.

    Combines the features of the standard QueryDSL JPQLQuery with the Holon QueryBuilder, allowing to seamlessy use the default core query architecture expressions (for example DataTarget, QueryFilter, QuerySort and QueryAggregation) for query definition.

    Provides some convenience methods to obtain query results providing a projection expression, such as list(Expression), singleResult(Expression), uniqueResult(Expression).

    The QueryDsl Datastore commodity can be used to obtain a new JpaQuery instance through the QueryDsl.query() method. Example: 

     JpaQuery q = getDatastore().create(QueryDsl.class).query();
    Since:
    5.1.0
