Soprano.Node createBlankNode | ( |  | self ) |

Will do nothing but set an Error.ErrorPermissionDenied error.

Soprano.QueryResultIterator executeQuery | ( | self, |
|  | QString | query,
|  | Soprano.Query.QueryLanguage | language,
|  | QString | userQueryLanguage=QString()
| ) |  |  |

Simply pipes the call through to the parent model.

bool isEmpty | ( |  | self ) |

Simply pipes the call through to the parent model.

Soprano.NodeIterator listContexts | ( |  | self ) |

Simply pipes the call through to the parent model.

Soprano.StatementIterator listStatements | ( | self, |
|  | Soprano.Statement | partial
| ) |  |  |

Default implementation simply pipes the call through to the parent model.

|  | Soprano.Model | model
| ) |  |  |

Set the parent Model.

Parameters:

  | model | The Model that this filter will forward any commands to.

int statementCount | ( |  | self ) |
