Method Detail

getRepository

public NativeRdfRepository getRepository()

Description copied from interface: NativeValue

Returns the NativeRdfRepository that contains this NativeValue. IDs are only unique within a single repository, but an application could use several repositories at the same time, passing NativeValue objects generated by one Sail to another Sail. In such situations, the ID of the first Sail cannot be used by the second Sail. Hence, the NativeRdfRepository should verify that it is the 'owner' of a value before using the recorded internal ID.

Specified by:

getRepository in interface NativeValue

setInternalId

public void setInternalId(int id,
                          ValueStoreRevision revision)

Description copied from interface: NativeValue

Sets the ID that is used for this value in a specific revision of the value store.

Specified by:

setInternalId in interface NativeValue

getInternalId

public int getInternalId()

Description copied from interface: NativeValue

Gets the ID that is used in the native RDF repository for this Value.

Specified by:

getInternalId in interface NativeValue

Returns:

The value's ID, or 0 if not yet set.

getValueStoreRevision

public ValueStoreRevision getValueStoreRevision()

Description copied from interface: NativeValue

Gets the revision of the value store that created this value. The value's internal ID is only valid when it's value store revision is equal to the value store's current revision.

Specified by:

getValueStoreRevision in interface NativeValue

Returns:

The revision of the value store that created this value, or null if the internal ID has not yet been set.

getSubjectStatements

public StatementIterator getSubjectStatements()
                                       throws GraphException

Description copied from interface: Resource

Gets all statements from the RDF graph for which this resource is the subject.

Specified by:

getSubjectStatements in interface Resource

Overrides:

getSubjectStatements in class URIImpl

Throws:

GraphException

getPredicateStatements

public StatementIterator getPredicateStatements()
                                         throws GraphException

Description copied from interface: URI

Gets all statements from the RDF graph for which this URI is the predicate.

Specified by:

getPredicateStatements in interface URI

Overrides:

getPredicateStatements in class URIImpl

Throws:

GraphException

getObjectStatements

public StatementIterator getObjectStatements()
                                      throws GraphException

Description copied from interface: Value

Gets all statements from the RDF graph for which this value is the object.

Specified by:

getObjectStatements in interface Value

Overrides:

getObjectStatements in class URIImpl

Throws:

GraphException

addProperty

public void addProperty(URI property,
                        Value value)
                 throws GraphException

Description copied from interface: Resource

Adds a property to this Resource in the RDF graph. The result is that a statement of the form (this, property, value) is added.

Specified by:

addProperty in interface Resource

Overrides:

addProperty in class URIImpl

Throws:

GraphException
