Class Summary

Class	Description
AsyncSearchResultImpl<T>	Default implementation of AsyncSearchResult based on an underlying HGSearchResult where each operation is submitted as a task to the HGEnvironment.executor().
DefaultKeyBasedQuery<Key,Value>
DelayedSetLoadPredicate	A predicate that check whether a handle is the member of a set of handles.
DerefMapping<T>
FilteredRAResultSet<T>
FilteredResultSet<T>	Filter a result set through a predicate.
HandleArrayResultSet	Implements a HGSearchResult comprising the atoms in a given HGHandle array.
IndexBasedQuery<T>	A simple query that operates on a single index.
IndexScanQuery<Key,Value>	This queries simply scans all elements in a given index.
InMemoryIntersectionResult<T>
InMemoryIntersectionResult.Combiner<T>
IntersectionQuery<T>	An IntersectionQuery combines the results of two underlying queries and produces a result set containing only elements that appear in both of the input result sets.
KeyBasedQuery<Key,Value>	A KeyBasedQuery is a HGQuery that produces a result based on a single key value.
LinkProjectionMapping
LinkTargetsResultSet	This is the same as HandleArrayResultSet, but it uses a loaded link atom instance instead of a HGHandle[].
MappedResult<From,To>	A MappedResult is a HGSearchResult with an applied transformation to each of its elements.
PipedResult<Key,Value>	A piped query result takes the output of a query, in the form of a HGSearchResult instance and uses it as input to a "pipe" query.
PipeQuery<Key,Value>	A PipeQuery pipes the output of one query as the input of another.
PredicateBasedFilter<T>	A HGQuery whose result is constructed by filtering the result set of another HGQuery according to a HGQueryCondition.
PredicateBasedRAFilter<T>	A HGQuery whose result is constructed by filtering the result set of another HGQuery according to a HGQueryCondition.
ProjectionAtomResultSet
RABasedPredicate	Make a random access result set as a predicate.
ResultMapQuery	A HGQuery that transforms the result of an underlying query by applying a provided mapping.
SearchableBasedQuery<Key,Value>	A simple query that operates on a single HGSearchable entity, usually a HGIndex.
SortedIntersectionResult<T>	Combines two ordered result sets into a (ordered) result representing their set theoretical intersection.
SortedIntersectionResult.Combiner<T>
SyncSearchResult<T>
TraversalBasedQuery
TraversalResult	TraversalResult wraps a graph HGTraversal as a query HGSearchResult.
TypeConditionAggregate
UnionQuery<T>	An UnionQuery combines the results of two underlying queries and produces a result set containing elements that appear in either of the input result sets.
UnionResult<T>	Combines two result set into a result representing their set theoretic union.
UnionResultAsync<T>
ZigZagIntersectionResult<T>	The ZigZagIntersectionResult operates on two sorted, random access result sets.
ZigZagIntersectionResult.Combiner<T>
