Interface IKeyArrayIndexProcedure

All Superinterfaces:

IIndexProcedure, Serializable

All Known Implementing Classes:

AbstractKeyArrayIndexProcedure, BatchContains, BatchInsert, BatchLookup, BatchRemove, Id2TermWriteProc, JustIndexWriteProc, MagicIndexWriteProc, SPOIndexWriteProc, Term2IdWriteProc, TextIndexWriteProc

public interface IKeyArrayIndexProcedure
extends IIndexProcedure

Interface for procedures that are mapped across one or more index partitions based on an array of keys. The keys are interpreted as variable length unsigned byte[]s and MUST be in sorted order. The ClientIndexView will transparently break down the procedure into one procedure per index partition based on the index partitions spanned by the keys.

Note: Implementations of this interface MUST declare an AbstractKeyArrayIndexProcedureConstructor that will be used to create the instances of the procedure mapped onto the index partitions.

Returns:

The keys and never null.

getValues

IRaba getValues()

The values.

Returns:

The values -or- null if no values were associated with the IIndexProcedure.
