Constructor Detail

EMFDataSource

public EMFDataSource(NavigationHelper navigationHelper,
                     java.util.Set<org.eclipse.emf.ecore.EReference> references,
                     java.util.Set<org.eclipse.emf.ecore.EClass> classes)

Parameters:

navigationHelper -

references -

classes - additional classes to treat as nodes. Source and target classes of references need not be added.

Method Detail

getAllNodes

public java.util.Set<org.eclipse.emf.ecore.EObject> getAllNodes()

Description copied from interface: IGraphDataSource

Get all nodes of the graph.

Specified by:

getAllNodes in interface IGraphDataSource<org.eclipse.emf.ecore.EObject>

Returns:

the set of all nodes

getTargetNodes

public java.util.List<org.eclipse.emf.ecore.EObject> getTargetNodes(org.eclipse.emf.ecore.EObject source)

Description copied from interface: IGraphDataSource

Get those nodes that are the target of an edge starting with source. List is returned as multiple edges may be present.

Specified by:

getTargetNodes in interface IGraphDataSource<org.eclipse.emf.ecore.EObject>

Parameters:

source - the source node

Returns:

the list of target nodes or null if no targets can be found

attachObserver

public void attachObserver(IGraphObserver<org.eclipse.emf.ecore.EObject> go)

Description copied from interface: IGraphDataSource

Attach a new graph observer. Note that the order of attaching the observers may be important (some observers will be notified earlier than others).

Specified by:

attachObserver in interface IGraphDataSource<org.eclipse.emf.ecore.EObject>

Parameters:

go - the graph observer

detachObserver

public void detachObserver(IGraphObserver<org.eclipse.emf.ecore.EObject> go)

Description copied from interface: IGraphDataSource

Detach an existing observer.

Specified by:

detachObserver in interface IGraphDataSource<org.eclipse.emf.ecore.EObject>

Parameters:

go - the graph observer

notifyEdgeInserted

public void notifyEdgeInserted(org.eclipse.emf.ecore.EObject source,
                               org.eclipse.emf.ecore.EObject target)

notifyEdgeDeleted

public void notifyEdgeDeleted(org.eclipse.emf.ecore.EObject source,
                              org.eclipse.emf.ecore.EObject target)

notifyNodeInserted

public void notifyNodeInserted(org.eclipse.emf.ecore.EObject node)

notifyNodeDeleted

public void notifyNodeDeleted(org.eclipse.emf.ecore.EObject node)
