public static final DataFlavor CLASS_NODE_FLAVOR

flavor used for drag and drop

Constructor Detail

ClassNode

public ClassNode(Ontology o)

Constructs a root class node from an ontology

Parameters:

o - the ontology

ClassNode

public ClassNode(OClass clas)

Constructs a class node given an ontology class

Parameters:

clas - ontology class

ClassNode

public ClassNode(OInstance instance)

Constructs a class node given an ontology instance

Parameters:

instance - ontology instance

ClassNode

public ClassNode(MappingNode mapNode)

Constructs a class node given a mapping node

Parameters:

mapNode - mapping node

Method Detail

createRootNode

public static ClassNode createRootNode(Ontology o)

create a structure representing the class hierarchy of an ontology

Returns:

the root node of the structure

createRootNode

public static ClassNode createRootNode(Ontology o,
                                       boolean includeInstances,
                                       boolean includeAnonymousClasses)

createRootNode

public static ClassNode createRootNode(Ontology o,
                                       MappingDefinition mapping,
                                       Map<String,ClassNode> nameVsNode)

Creates a structure representing the class hierarchy of an ontology and the gazetteerLists mapped to it.

Parameters:

o - an ontology

mapping - mapping definition

nameVsNode - : this is actually a return value: should be initialized before passing to this method and afterwards one can find a mapping of class names vs class nodes there.

Returns:

the root node of the structure
