Uses of HGQuery in org.hypergraphdb.query.impl

Subclasses of HGQuery in org.hypergraphdb.query.impl

class	DefaultKeyBasedQuery
class	IndexBasedQuery A simple query that operates on a single index.
class	IndexScanQuery This queries simply scans all elements in a given index.
class	IntersectionQuery 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.
class	KeyBasedQuery A KeyBasedQuery is a HGQuery that produces a result based on a single key value.
class	PipeQuery A PipeQuery pipes the output of one query as the input of another.
class	PredicateBasedFilter A HGQuery whose result is constructed by filtering the result set of another HGQuery according to a HGQueryCondition.
class	ResultMapQuery A HGQuery that transforms the result of an underlying query by applying a provided mapping.
class	SearchableBasedQuery A simple query that operates on a single HGSearchable entity, usually a HGIndex.
class	TraversalBasedQuery
class	UnionQuery 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.
