org.ontoware.rdf2go.model.Model.removeStatements()
org.openrdf.sail.NotifyingSailConnection.removeStatements()
org.openrdf.sail.SailConnection.removeStatements()
Removes all statements matching the specified subject, predicate and object from the repository. All three parameters may be null to indicate wildcards. @param subj The subject of the statement that should be removed, or null to indicate a wildcard. @param pred The predicate of the statement that should be removed, or null to indicate a wildcard. @param obj The object of the statement that should be removed , or null to indicate a wildcard. @param contexts The context(s) from which to remove the statement. Note that this parameter is a vararg and as such is optional. If no contexts are specified the method operates on the entire repository. A null value can be used to match context-less statements. @throws StoreException If the statement could not be removed.
