Method Detail

translateToGraph

protected 
Rectangle translateToGraph(
Rectangle r)
Description copied from class: org.eclipse.gmf.runtime.diagram.ui.providers.internal.DefaultProvider
Retrieves the extent and position from the given logical rectangle in GEF graph coordinates. Defined as abstract to allow subclasses to implement to perform a transformation on the values stored in the node. i.e. support for Left-Right layout as opposed to Top-Down.

Specified by:
translateToGraph in class org.eclipse.gmf.runtime.diagram.ui.providers.internal.DefaultProvider
Returns:
Rectangle in graph coordinates.

translateFromGraph

protected 
Rectangle translateFromGraph(
Rectangle rect)
Description copied from class: org.eclipse.gmf.runtime.diagram.ui.providers.internal.DefaultProvider
Retrieves the logical extent and position from the given rectangle. Defined as abstract to allow subclasses to implement to perform a transformation on the values stored in the node. i.e. support for Left-Right layout as opposed to Top-Down.

Specified by:
translateFromGraph in class org.eclipse.gmf.runtime.diagram.ui.providers.internal.DefaultProvider
Parameters:
rect - Rectangle that has the values to be translated in graph (pixel) coordinates.
Returns:
Rectangle in logical coordinates.

createGraph

protected 
DirectedGraph createGraph()
Description copied from class: org.eclipse.gmf.runtime.diagram.ui.providers.internal.DefaultProvider
Creates the graph that will be used by the layouy provider Clients can override this method create different kind of graphs This method is called by DefaultProvider.layoutEditParts(GraphicalEditPart, IAdaptable) and DefaultProvider.layoutEditParts(List, IAdaptable)

Overrides:
createGraph in class org.eclipse.gmf.runtime.diagram.ui.providers.internal.DefaultProvider
Returns:
the Graph that will be used by the layout algorithm
