org.apache.jena.ontapi.common.CommonEnhNodeFactoryImpl

All Implemented Interfaces:

EnhNodeFactory

public class CommonEnhNodeFactoryImpl
extends BaseEnhNodeFactoryImpl

Default implementation of EnhNodeFactory. This is a kind of constructor that consists of three modules:

• EnhNodeProducer for initialization and physical creation a node EnhNode in the graph EnhGraph.
• EnhNodeFilter to test the presence of a node in the graph.
• EnhNodeFinder to search for nodes in the graph.

Method Summary

Modifier and Type	Method	Description
boolean	canCreateInGraph(org.apache.jena.graph.Node node, org.apache.jena.enhanced.EnhGraph eg)	Answers true iff the modifying of the graph is allowed by this implementation for the encapsulated object's interface.
boolean	canWrap(org.apache.jena.graph.Node node, org.apache.jena.enhanced.EnhGraph eg)	Checks that the wrapping (node, eg) would succeed.
org.apache.jena.enhanced.EnhNode	createInGraph(org.apache.jena.graph.Node node, org.apache.jena.enhanced.EnhGraph eg)	Makes interface-defined changes in the given graph and returns a new enhanced node, wrapping the given Node.
org.apache.jena.enhanced.EnhNode	createInstance(org.apache.jena.graph.Node node, org.apache.jena.enhanced.EnhGraph eg)	Wraps the given pair of node and graph to a fresh EnhNode instance without any checking or throwing any exception.

public EnhNodeFinder getFinder()

getFilter

public EnhNodeFilter getFilter()

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

createInGraph

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

Description copied from interface: EnhNodeFactory

Makes interface-defined changes in the given graph and returns a new enhanced node, wrapping the given Node.

Parameters:

node - Node, the node to be wrapped as EnhNode, not null

eg - EnhGraph, the graph which would contain the result EnhNode, not null

Returns:

a new enhanced node

canCreateInGraph

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

Description copied from interface: EnhNodeFactory

Answers true iff the modifying of the graph is allowed by this implementation for the encapsulated object's interface.

Parameters:

node - Node the node to test that changes are permitted.

eg - EnhGraph the graph to be changed.

Returns:

true if creation is allowed.

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

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
