Class MaterializedDoubleRelation

  • All Implemented Interfaces:
    elki.database.relation.DoubleRelation, elki.database.relation.ModifiableRelation<java.lang.Double>, elki.database.relation.Relation<java.lang.Double>
    public class MaterializedDoubleRelation
extends java.lang.Object
implements elki.database.relation.DoubleRelation
    Represents a single representation. This is attached to a DBIDs object, which you are supposed to manage first. I.e. put the new DBID in, then invoke set(), remove the DBID, then delete().
