See getMemValue() for description. | | public Set<MemBNode> | getMemBNodes()
Gets all bnodes that are managed by this value factory. | | public MemLiteral | getMemLiteral(Literal literal)
See getMemValue() for description. | | public Set<MemLiteral> | getMemLiterals()
Gets all literals that are managed by this value factory. | | public MemResource | getMemResource(Resource resource)
See getMemValue() for description. | | public MemURI | getMemURI(URI uri)
See getMemValue() for description. | | public Set<MemURI> | getMemURIs()
Gets all URIs that are managed by this value factory. | | public MemValue | getMemValue(Value value)
Returns a previously created MemValue that is equal to the supplied value,
or null if the supplied value is a new value or is equal to
null.
Parameters:
value - The MemValue equivalent of the supplied value, or null. |
| createMemBNode | | public MemBNode createMemBNode(BNode bnode)(Code) | | See createMemValue() for description.
|
| createMemURI | | public MemURI createMemURI(URI uri)(Code) | | See createMemValue() for description.
|
| createMemValue | | public MemValue createMemValue(Value value)(Code) | | Creates a MemValue for the supplied Value. The supplied value should not
already have an associated MemValue. The created MemValue is returned.
Parameters:
value - A Resource or Literal. The created MemValue. |
| getMemBNodes | | public Set<MemBNode> getMemBNodes()(Code) | | Gets all bnodes that are managed by this value factory.
An unmodifiable Set of MemBNode objects. |
| getMemLiterals | | public Set<MemLiteral> getMemLiterals()(Code) | | Gets all literals that are managed by this value factory.
An unmodifiable Set of MemURI objects. |
| getMemURI | | public MemURI getMemURI(URI uri)(Code) | | See getMemValue() for description.
|
| getMemURIs | | public Set<MemURI> getMemURIs()(Code) | | Gets all URIs that are managed by this value factory.
An unmodifiable Set of MemURI objects. |
| getMemValue | | public MemValue getMemValue(Value value)(Code) | | Returns a previously created MemValue that is equal to the supplied value,
or null if the supplied value is a new value or is equal to
null.
Parameters:
value - The MemValue equivalent of the supplied value, or null. A previously created MemValue that is equal to value,or null if no such value exists or if valueis equal to null. |
