Fetchable<T>	Fetchable defines default projection methods for Query implementations.
FetchableQuery<T,Q extends FetchableQuery<T,Q>>	FetchableQuery extends Fetchable and SimpleQuery with projection changing methods and result aggregation functionality using ResultTransformer instances.
FilteredClause<C extends FilteredClause<C>>	FilteredClause is an interface for clauses with a filter condition
Query<Q extends Query<Q>>	Query defines the main query interface of the fluent query language.
QueryFactory<Q extends Query<?>>	Common interface for QueryFactory implementations
QueryMetadata	QueryMetadata defines query metadata such as query sources, filtering conditions and the projection
ResultTransformer<T>	Executes query on a FetchableQuery and transforms results into T.
SimpleQuery<Q extends SimpleQuery<Q>>	SimpleQuery defines a simple querying interface than Query
