Module org.apache.jena.core

Package org.apache.jena.memvalue

Class GraphMemValue

java.lang.Object

org.apache.jena.graph.impl.GraphBase

org.apache.jena.memvalue.GraphMemValue

All Implemented Interfaces:

Graph, GraphWithPerform

@Deprecated
public class GraphMemValue
extends GraphBase

Deprecated.

Applications should be using GraphMemFactory.createDefaultGraph() for a general purpose graph or GraphMemFactory.createDefaultGraphSameValue() if necessary implementation.

In-memory, non-thread-safe, non-transactional graph. This specialised graph has same-value semantics for literals. It is used in the ModelAPI : see GraphMemFactory.createGraphMemForModel().

Method Details

performAdd

public void performAdd(Triple t)

Deprecated.

Description copied from class: GraphBase

Add a triple to the triple store. The default implementation throws an AddDeniedException; subclasses must override if they want to be able to add triples.

Specified by:

performAdd in interface GraphWithPerform

Overrides:

performAdd in class GraphBase

performDelete

public void performDelete(Triple t)

Deprecated.

Description copied from class: GraphBase

Remove a triple from the triple store. The default implementation throws a DeleteDeniedException; subclasses must override if they want to be able to remove triples.

Specified by:

performDelete in interface GraphWithPerform

Overrides:

performDelete in class GraphBase

graphBaseSize

public int graphBaseSize()

Deprecated.

graphBaseFind

public ExtendedIterator<Triple> graphBaseFind(Triple m)

Deprecated.

Answer an ExtendedIterator over all the triples in this graph that match the triple-pattern m. Delegated to the store.

graphBaseContains

public boolean graphBaseContains(Triple t)

Deprecated.

Answer true iff this graph contains t. If t happens to be concrete, then we hand responsibility over to the store. Otherwise we use the default implementation.

clear

public void clear()

Deprecated.

Clear this GraphMem, ie remove all its triples (delegated to the store).

Specified by:

clear in interface Graph

Overrides:

clear in class GraphBase

stream

public Stream<Triple> stream(Node s,
 Node p,
 Node o)

Deprecated.

Description copied from interface: Graph

Returns a Stream of Triples matching a pattern.

Returns:

a stream of triples in this graph matching the pattern.

clearStore

public void clearStore()

Deprecated.

Clear this GraphMem, ie remove all its triples (delegated to the store).
