Interface Summary

Interface	Description
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
Tuple	Tuple defines an interface for generic query result projection

DefaultQueryMetadata	DefaultQueryMetadata is the default implementation of the QueryMetadata interface.
EmptyMetadata	EmptyMetadata provides an immutable empty QueryMetadata instance.
JoinExpression	JoinExpression is a join element in a Query instance.
JoinFlag	JoinFlag defines a join related flag using an Expression instance
QueryFlag	Defines a positioned flag in a Query for customization of query serialization
QueryModifiers	QueryModifiers combines limit and offset info into a single immutable value type.
