Constructor Details

CompositeEnhNodeFactoryImpl

public CompositeEnhNodeFactoryImpl(EnhNodeFinder finder,
 EnhNodeFilter fittingFilter,
 EnhNodeFactory... factories)

Creates a factory instance.

Parameters:

finder - EnhNodeFinder, optional, if null then uses only provided sub-factories to search

fittingFilter - EnhNodeFilter, optional, to trim searching

factories - array of factories to combine, must not be null or empty

Method Details

wrap

public org.apache.jena.enhanced.EnhNode wrap(org.apache.jena.graph.Node node,
 org.apache.jena.enhanced.EnhGraph eg)

Description copied from class: BaseEnhNodeFactoryImpl

Creates a new EnhNode wrapping the given Node node in the context of the graph EnhGraph.

Specified by:

wrap in interface EnhNodeFactory

Overrides:

wrap in class BaseEnhNodeFactoryImpl

Parameters:

node - the node to be wrapped

eg - the graph containing the node

Returns:

A new enhanced node which wraps node but presents the interface(s) that this factory encapsulates.

canWrap

public boolean canWrap(org.apache.jena.graph.Node node,
 org.apache.jena.enhanced.EnhGraph eg)

Description copied from interface: EnhNodeFactory

Checks that the wrapping (node, eg) would succeed.

Specified by:

canWrap in interface EnhNodeFactory

Specified by:

canWrap in class org.apache.jena.enhanced.Implementation

Parameters:

node - node the node to test for suitability

eg - the enhanced graph the node appears in

Returns:

true iff the node can represent the type in the graph

createInstance

public org.apache.jena.enhanced.EnhNode createInstance(org.apache.jena.graph.Node node,
 org.apache.jena.enhanced.EnhGraph eg)

Description copied from interface: EnhNodeFactory

Wraps the given pair of node and graph to a fresh EnhNode instance without any checking or throwing any exception. Some implementations may return null if the EnhNodeFactory.canWrap(Node, EnhGraph) returns false. Unlike the method EnhNodeFactory.createInGraph(Node, EnhGraph), this method does not make any changes to the graph.

Parameters:

node - Node, not null

eg - EnhGraph, not null

Returns:

EnhNode or null

iterator

public org.apache.jena.util.iterator.ExtendedIterator<org.apache.jena.enhanced.EnhNode> iterator(org.apache.jena.enhanced.EnhGraph eg)

Description copied from interface: EnhNodeFactory

Returns an Extended Iterator over the nodes found in the EnhGraph in the form of EnhNode with the interface that this factory encapsulates. It is assumed that the returned iterator is distinct (does not answer with duplicates). At least, it must be distinct if the EnhGraph encapsulates the distinct graph (see also Graphs.isDistinct(Graph)).

Parameters:

eg - EnhGraph

Returns:

ExtendedIterator of EnhNodes

getFinder

public EnhNodeFinder getFinder()

getFilter

public EnhNodeFilter getFilter()

listFactories

public org.apache.jena.util.iterator.ExtendedIterator<? extends EnhNodeFactory> listFactories()

Lists all sub-factories.

Returns:

ExtendedIterator of EnhNodeFactory
