/**
 * This package defines the {@link org.apache.isis.applib.query.Query} interface
 * and supporting implementations.
 * 
 * <p>
 * The {@link org.apache.isis.applib.query.Query} concept is provided as a
 * standardized mechanism by which 
 * {@link org.apache.isis.applib.AbstractFactoryAndRepository repositories}
 * or indeed any {@link org.apache.isis.applib.AbstractDomainObject domain object}
 * can submit.  Object store implementation are generally expected to support
 * the {@link org.apache.isis.applib.query.QueryBuiltInAbstract built-in queries},
 * meaning that there may not be any need to provide different implementations
 * of the repositories.  (This provides some of the benefits that .NET has
 * with its LINQ technology, though it is admittedly nowhere near as 
 * sophisticated).
