All Known Subinterfaces:

MultiIndex<ST,T,PK,V,S>, OrderedIndex<ST,T,PK,V,S>, UniqueIndex<ST,T,PK,V,S>

All Known Implementing Classes:

AbstractIndex

public interface Index<ST,T extends ST,PK,V,S extends Store<ST,PK,S>>
extends Iterable<T>

Store.addIndex() returns object which implements one or more of Index sub-interfaces. Index instances are used to directly leverage index functionality without going through Store.get() methods.
