Method Detail

fireResourceLoaded

protected void fireResourceLoaded(org.eclipse.emf.common.util.URI uri)

create

public Controller create(SymbolController controller,
                         Primitive element)
                  throws Exception

Throws:

Exception

create

public org.eclipse.draw2d.geometry.Rectangle create(Position position,
                                                    Dimension dimension)

load

protected XMISymbolLoader load(String stringUri)
                        throws Exception

Loads a new symbol based on the current symbol/resource context

Note that the implementation caches by URI

Parameters:

uri - the URI from where to load the symbol

Returns:

a symbol loader

Throws:

Exception - if anything goes wrong

getRoot

public SymbolLoader getRoot()

createSubFactory

public BasicViewElementFactory createSubFactory(SymbolLoader symbolLoader)

Create a new factory with the resource root based on the provided symbol loader

Since the factory holds a reference to the symbol loader, which is the context for resolving resource URIs, a new factory must be created for every child symbol.

Parameters:

symbolLoader - symbol loader, resource context for the new factory

Returns:

a new factory

createConnections

public void createConnections(org.eclipse.draw2d.Layer layer,
                              SymbolController controller,
                              org.eclipse.emf.common.util.EList<Connection> connections)
