Uses of HGIndex in org.hypergraphdb

Subinterfaces of HGIndex in org.hypergraphdb

Modifier and Type	Interface and Description
interface	HGBidirectionalIndex<KeyType,ValueType> A HGBidirectionalIndex provides efficient searching of an index entry by value as well as by key.
interface	HGSortIndex<KeyType,ValueType> A HGSortIndex is a HGIndex that maintains its keys in an order relation.
