Method Detail
-
getDefaultRemoveGraphs
public Set<IRI> getDefaultRemoveGraphs()
Description copied from interface:DatasetGets the default remove graph URIs of this dataset. An empty set indicates the the store's default behaviour should be used, if not otherwise indicated in the operation.- Specified by:
getDefaultRemoveGraphsin interfaceDataset
-
addDefaultRemoveGraph
public void addDefaultRemoveGraph(IRI graphURI)
Adds a graph URI to the set of default remove graph URIs.
-
removeDefaultRemoveGraph
public boolean removeDefaultRemoveGraph(IRI graphURI)
Removes a graph URI from the set of default remove graph URIs.- Returns:
- true if the URI was removed from the set, false if the set did not contain the URI.
-
getDefaultInsertGraph
public IRI getDefaultInsertGraph()
Description copied from interface:DatasetGets the default insert graph URI of this dataset. An null value indicates that the store's default behaviour should be used, if not otherwise indicated in the operation.- Specified by:
getDefaultInsertGraphin interfaceDataset- Returns:
- Returns the default insert graph.
-
setDefaultInsertGraph
public void setDefaultInsertGraph(IRI defaultInsertGraph)
- Parameters:
defaultInsertGraph- The default insert graph to used.
-
getDefaultGraphs
public Set<IRI> getDefaultGraphs()
Description copied from interface:DatasetGets the default graph URIs of this dataset. An empty default graph set and a non-empty named graph set indicates that the default graph is an empty graph. However, if both the default graph set and the named graph set are empty, that indicates that the store's default behaviour should be used.- Specified by:
getDefaultGraphsin interfaceDataset
-
addDefaultGraph
public void addDefaultGraph(IRI graphURI)
Adds a graph URI to the set of default graph URIs.
-
removeDefaultGraph
public boolean removeDefaultGraph(IRI graphURI)
Removes a graph URI from the set of default graph URIs.- Returns:
- true if the URI was removed from the set, false if the set did not contain the URI.
-
getNamedGraphs
public Set<IRI> getNamedGraphs()
Gets the (unmodifiable) set of named graph URIs.- Specified by:
getNamedGraphsin interfaceDataset
-
addNamedGraph
public void addNamedGraph(IRI graphURI)
Adds a graph URI to the set of named graph URIs.
-
removeNamedGraph
public boolean removeNamedGraph(IRI graphURI)
Removes a graph URI from the set of named graph URIs.- Returns:
- true if the URI was removed from the set, false if the set did not contain the URI.
-
clear
public void clear()
Removes all graph URIs (both default and named) from this dataset.
