Delete all statements whose subject is one of the resources's URis.
|
void |
deleteResources(URI namedGraphUri,
URI... nodeUris)
Delete all statements whose subject is one of nodeUris
|
com.hp.hpl.jena.rdf.model.Model |
getJenaModelForSubject(URI namedGraphUri,
URI subject)
Retrieve a Jena model for triples under the given subject from the corresponding named graph.
|
<T extends org.eclipse.lyo.oslc4j.core.model.IResource> |
getResource(URI namedGraph,
URI uri,
Class<T> clazz)

IResource instance specified by the concrete
type, unmarshaled from the RDF graph persisted in the triplestore under the given
named graph. |
<T extends org.eclipse.lyo.oslc4j.core.model.IResource> |
getResources(URI namedGraph,
Class<T> clazz)
Retrieve the collection of
IResource instances specified by the concrete
type, unmarshaled from the RDF graph persisted in the triplestore under the given
named graph. |
<T extends org.eclipse.lyo.oslc4j.core.model.IResource> |
getResources(URI namedGraph,
Class<T> clazz,
int limit,
int offset)
Alternative to
Store.getResources(URI, Class) with paging on the OSLC resource level. |
void |
insertJenaModel(URI name,
com.hp.hpl.jena.rdf.model.Model model)
Insert a jena model into the named graph with corresponding URI.
|
boolean |
insertResources(URI namedGraph,
Object... resources)
Insert Jena models representations of OSLC
IResource instances into the
named graph. |
Set<String> |
keySet()
Enumerates all named graph URIs within the dataset.
|
boolean |
namedGraphExists(URI namedGraph)
Checks if the triplestore has the named graph under the corresponding URI.
|
boolean |
putResource(URI namedGraphUri,
org.eclipse.lyo.oslc4j.core.model.IResource resource) |
<T extends org.eclipse.lyo.oslc4j.core.model.IResource> |
putResources(URI namedGraph,
Collection<T> resources)
Inserts OSLC
IResource instances into the triplestore in the designed
namedGraph. |
void |
removeAll()
Remove EVERYTHING from the triplestore.
|
boolean |
resourceExists(URI namedGraphUri,
URI resourceUri)
Checks if a resource with resourceUri exists under the corresponding named graph.
