All Implemented Interfaces:

org.apache.jena.atlas.lib.Closeable, org.apache.jena.atlas.lib.Sync, DatasetPrefixStorage

public class DatasetPrefixesTDB
extends Object
implements DatasetPrefixStorage

Dataset prefixes; a table of nodes with prefix-centric operations. The table is G-P-U where G is a graph name as a URI (a URI for <> is used for the default graph), P is a string (the prefix) and U is the IRI.
