getNodeCache

protected org.apache.jena.atlas.lib.Cache<org.apache.jena.graph.Node,org.apache.jena.rdf.model.RDFNode> getNodeCache()

Returns nodes cache.

Returns:

Cache with Node as key and RDFNode as value

isLocal

public boolean isLocal(org.apache.jena.rdf.model.Statement s)

Answers true if the given statement belongs to the base graph.

Parameters:

s - Statement, not null

Returns:

boolean

isLocal

public boolean isLocal(org.apache.jena.rdf.model.Resource s,
                       org.apache.jena.rdf.model.Property p,
                       org.apache.jena.rdf.model.RDFNode o)

Answers true if the given SPO belongs to the base graph.

Parameters:

Returns a RDFNode for the given type and, if the result is present, caches it node at the model level. The method works silently: normally no exception is expected.

Type Parameters:

N - any subtype of RDFNode

Parameters:

node - Node

type - Class-type

Returns:

RDFNode or null

Throws:

RuntimeException - unexpected misconfiguration (RDF recursion, wrong input, personality mismatch, etc)

Answers an enhanced node that wraps the given node and conforms to the given interface type. The returned RDF node is cached at the model-level.

Overrides:

getNodeAs in class org.apache.jena.enhanced.EnhGraph

Type Parameters:

N - a subtype of RDFNode

Parameters:

node - a node (assumed to be in this graph)

type - a type denoting the enhanced facet desired

Returns:

an enhanced node, cannot be null

Throws:

OntJenaException - unable to construct new RDF view for whatever reasons

Type Parameters:

N - a subtype of RDFNode

Parameters:

node - a node (assumed to be in this graph)

type - a type denoting the enhanced facet desired

Returns:

an enhanced node or null if no match found
