Interface IDBID

All Known Implementing Classes:

DBIDInt, DBIDHash

public interface IDBID

Interface for database identifiers. Most RDF entities (resources, literals, statements) have an associated database index. These are cached using RDB-specific variants of the jena "impl" classes. This can avoid some redundant database lookup.

In simple implementations the database identifier is simply an integer given a database row index allocated by some generator. In other implementations we use a "unique" hash of the resource or literal data itself. This interface encapsulates the different ID representations.
