IThreadSafeDataset Interface |
Interface for SPARQL Datasets which also provide a Lock by which threading can be controlled.
Namespace: VDS.RDF.Query.Datasets
Assembly: dotNetRDF (in dotNetRDF.dll) Version:
SyntaxThe IThreadSafeDataset type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | ActiveGraphUris |
Gets the enumeration of the Graph URIs that currently make up the active graph.
(Inherited from ISparqlDataset.) |
| DefaultGraphUris |
Gets the enumeration of the Graph URIs that currently make up the default graph.
(Inherited from ISparqlDataset.) |
| Graphs |
Gets all the Graphs in the Dataset.
(Inherited from ISparqlDataset.) |
| GraphUris |
Gets all the URIs of Graphs in the Dataset.
(Inherited from ISparqlDataset.) |
| HasTriples |
Gets whether the Dataset has any Triples.
(Inherited from ISparqlDataset.) |
| Item |
Gets the Graph with the given URI from the Dataset.
(Inherited from ISparqlDataset.) |
| Lock |
Gets the Lock used to ensure MRSW concurrency of the Dataset when used with the Leviathan SPARQL processors.
|
| Triples |
Gets all the Triples in the Dataset.
(Inherited from ISparqlDataset.) |
| UsesUnionDefaultGraph |
Gets whether the Default Graph is treated as being the union of all Graphs in the dataset when no Default Graph is otherwise set.
(Inherited from ISparqlDataset.) |
Methods| Name | Description | |
|---|---|---|
 | AddGraph |
Adds a Graph to the Dataset.
(Inherited from ISparqlDataset.) |
| ContainsTriple |
Gets whether the Dataset contains a specific Triple.
(Inherited from ISparqlDataset.) |
| Discard |
Ensures that any changes to the Dataset (if any) are discarded.
(Inherited from ISparqlDataset.) |
| Flush |
Ensures that any changes to the Dataset (if any) are flushed to the underlying Storage.
(Inherited from ISparqlDataset.) |
| GetModifiableGraph |
Gets the Graph with the given URI from the Dataset.
(Inherited from ISparqlDataset.) |
| GetTriplesWithObject |
Gets all the Triples in the Dataset with the given Object.
(Inherited from ISparqlDataset.) |
| GetTriplesWithPredicate |
Gets all the Triples in the Dataset with the given Predicate.
(Inherited from ISparqlDataset.) |
| GetTriplesWithPredicateObject |
Gets all the Triples in the Dataset with the given Predicate and Object.
(Inherited from ISparqlDataset.) |
| GetTriplesWithSubject |
Gets all the Triples in the Dataset with the given Subject.
(Inherited from ISparqlDataset.) |
| GetTriplesWithSubjectObject |
Gets all the Triples in the Dataset with the given Subject and Object.
(Inherited from ISparqlDataset.) |
| GetTriplesWithSubjectPredicate |
Gets all the Triples in the Dataset with the given Subject and Predicate.
(Inherited from ISparqlDataset.) |
| HasGraph |
Gets whether a Graph with the given URI is the Dataset.
(Inherited from ISparqlDataset.) |
| RemoveGraph |
Removes a Graph from the Dataset.
(Inherited from ISparqlDataset.) |
| ResetActiveGraph |
Resets the Active Graph to the previous Active Graph.
(Inherited from ISparqlDataset.) |
| ResetDefaultGraph |
Resets the Default Graph to the previous Default Graph.
(Inherited from ISparqlDataset.) |
| SetActiveGraph(IEnumerableUri) |
Sets the Active Graph to be the merge of the Graphs with the given URIs.
(Inherited from ISparqlDataset.) |
| SetActiveGraph(Uri) |
Sets the Active Graph to be the Graph with the given URI.
(Inherited from ISparqlDataset.) |
| SetDefaultGraph(IEnumerableUri) |
Sets the Default Graph to be the merge of the Graphs with the given URIs.
(Inherited from ISparqlDataset.) |
| SetDefaultGraph(Uri) |
Sets the Default Graph to be the Graph with the given URI.
(Inherited from ISparqlDataset.) |
Remarks
Note that there is no guarantees that consuming code will respect the fact that a Dataset is Thread Safe and use the Lock property appropriately. Additionally some datasets may choose to implement thread safety in other ways which don't rely on this interface.
