Uses of HGIndex in org.hypergraphdb

Subinterfaces of HGIndex in org.hypergraphdb

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.

Methods in org.hypergraphdb that return HGIndex

<KeyType,ValueType> HGIndex<KeyType,ValueType>	HGStore.createIndex(java.lang.String name, ByteArrayConverter<KeyType> keyConverter, ByteArrayConverter<ValueType> valueConverter, java.util.Comparator<?> comparator) Create a new index with the specified name.
<KeyType,ValueType> HGIndex<KeyType,ValueType>	HGIndexManager.getIndex(HGIndexer indexer) Retrieve the storage HGIndex associated to the passed-in HGIndexer.
<KeyType,ValueType> HGIndex<KeyType,ValueType>	HGStore.getIndex(java.lang.String name, ByteArrayConverter<KeyType> keyConverter, ByteArrayConverter<ValueType> valueConverter, java.util.Comparator comparator) Retrieve an HGIndex by its name.
HGIndex<HGPersistentHandle,HGPersistentHandle>	HGIndexManager.getIndexByType() Return the predefined index from types to atoms.
HGIndex<HGPersistentHandle,HGPersistentHandle>	HGIndexManager.getIndexByValue() Return the predefined index from values to atoms.
<KeyType,ValueType> HGIndex<KeyType,ValueType>	HGIndexManager.register(HGIndexer indexer) Possibly create a new index based on the specified IndexDescriptor.
