All Implemented Interfaces:

junit.framework.Test

public class TestSPOKeyCoders
extends TestCase2

Test suite for approaches to key compression for statement indices (keys are permutations on SPOC, logically comprised of long[4] and encoded as byte[]), the terms index (key is byte[] encoding the URI, literal, or bnode ID), or the ids index (key is byte[] encoding a long term identifier). Key compression can be used (a) before sorting the data; (b) when serializing the data for a remote operation on a data service; and (c) in the nodes and leaves of the indices themselves.
