Class ListIndexExtension<V extends com.bigdata.rdf.model.BigdataValue>

java.lang.Object

com.blazegraph.gremlin.internal.ListIndexExtension<V>

All Implemented Interfaces:

com.bigdata.rdf.internal.IExtension<V>

public class ListIndexExtension<V extends com.bigdata.rdf.model.BigdataValue>
extends Object
implements com.bigdata.rdf.internal.IExtension<V>

Effective, packed representation of property graph list index typed as <http://www.blazegraph.com/rdf/datatype#listIndex> Builds on the PackedLongIV datatype for representing timestamps, thus supporting the range [0;72057594037927935L]. Used for Cardinality.list vertex properties.
