Interface Remover


  • public interface Remover

    Interface for an object which can remove RDF data from a Stardog database.

    Usage:

    // remove a single statement c.remove().statements(s,p,o); // we can remove an entire context c.remove().context(cxt);

    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.

        Remover statements​(Resource theSubj,
                           IRI thePred,

                    throws StardogException
        Remove a statement or statements from the database; null's can be used in any position to indicate a wildcard matching anything in that position, thereby removing multiple statements. If contexts are specified, all statements matching the given SPO pattern will be removed from each context.
        Parameters:
        theSubj - the subject, or null for a wildcard
        thePred - the predicate, or null for a wildcard
        theObj - the object, or null for a wildcard
        theContexts - the context, or null for a wildcard
        Returns:
        this remover

      • context

        Remover context​(Resource theContext)
                 throws StardogException
        Remove the context and all the statements within from the database. If the context is Contexts.DEFAULT, this will remove the default graph (no context). If you want to remove everything in the database regardless of context, use all().
        Parameters:
        theContext - the context to remove
        Returns:
        this remover
        Throws:

               throws StardogException
        Remove the specified graph from the database. If contexts are specified, any context specified on the statements within the graph are ignored.

        theGraph - the graph to remove
        theContext - the optional context to remove from
        Returns:
        this remover
