Interface ISpaceIndex

All Superinterfaces:
Externalizable, ISwapExternalizable, Serializable, SmartExternalizable, SpaceIndex
All Known Implementing Classes:
AbstractSpaceIndex, CompoundIndex, CustomIndex, SpaceCollectionIndex, SpacePathIndex, SpacePropertyIndex
public interface ISpaceIndex extends SpaceIndex, SmartExternalizable, ISwapExternalizable

Encapsulates information about an index in a space type. Index defines how the objects of this class are stored: Index can be:

  • basic - supports efficiently equality queries.
  • extended - supports range queries

    Index also defines how the index value is extracted from the given entry.

    Usage example:
    @SpaceIndex(path="personalInfo.address")
