Node/edge type definition in booggie for visualization with yEd?

This is how a node type definition (has to be named YEdNode) with some yEd-attribute definitions looks like:

node class YEdNode{ height: int = 50; width: int = 100; x: int = 0; y: int = 0; color : string = "#FFFFFF"; shape : Shape = Shape::RECTANGLE; label : string = ""; } 

And the same for an edge type definition (has to be named YEdEdge):

edge class YEdEdge{ color : string = "#000000"; lineWidth: int = 2; label : string =""; lineType : string = "line"; } 

The shape-ENUM should look like that:

enum Shape {RECTANGLE, ROUNDRECTANGLE, ELLIPSE, PARALLELOGRAM, HEXAGON, TRIANGLE, RECTANGLE3D, OCTAGON, DIAMOND, TRAPEZOID, TRAPEZOID2}
