Interface Adder

public interface Adder

Interface for adding RDF to a Stardog database via a connection.

Usage:

// some stuff from a file c.add().io().format(RDFFormat.TURTLE).file(new File("data.ttl")); // also add something from some input stream c.add().io().format(RDFFormat.RDFXML).stream(input); // or add a specific statement c.add().statement(s,p,o);

The changes done through this class might not be sent immediately to the server. The client connection may batch the changes locally and delay sending those changes to the server to minimize the number of network calls. This is an implementation detail and will not change the execution order of read and write operations performed within the transaction.
