Interface Summary

Interface	Description
BackendQuery<Q extends BackendQuery>	A BackendQuery is a query that can be updated to a new limit.
ElementQuery<R extends JanusGraphElement,B extends BackendQuery<B>>	A query that returns JanusGraphElements.
Query	Standard Query interface specifying that a query may have a limit.
QueryExecutor<Q extends ElementQuery,R extends JanusGraphElement,B extends BackendQuery>	Executes a given query and its subqueries against an underlying data store and transaction.
QueryUtil.IndexCall<R>

Class Summary

Class	Description
BackendQueryHolder<E extends BackendQuery<E>>	Holds a BackendQuery and captures additional information that pertains to its execution and to be used by a QueryExecutor: Whether the query is fitted, i.e., whether all results returned from executing the backend query are part of the result set or must be filtered in memory.
BaseQuery	Standard implementation of Query.
JanusGraphPredicateUtils
LimitAdjustingIterator<R>	An iterator implementation that wraps around another iterator to iterate it up to a given limit.
MetricsQueryExecutor<Q extends ElementQuery,R extends JanusGraphElement,B extends BackendQuery>	Wraps a QueryExecutor to gather metrics on the query execution and forward them to METRICS.
QueryProcessor<Q extends ElementQuery<R,B>,R extends JanusGraphElement,B extends BackendQuery<B>>	Executes a given ElementQuery against a provided QueryExecutor to produce the result set of elements.
QueryUtil	Utility methods used in query optimization and processing.
ResultMergeSortIterator<R>
ResultSetIterator<R extends JanusGraphElement>	Wraps around a result set iterator to return up to the specified limit number of elements and implement the Iterator.remove() method based on element's remove method.
