circularRef

protected boolean circularRef(BModelNode startNode,
                              String arcType)

checks to see if there is a circular reference with this node, for a given arc type.

getXFormedBounds

public final Rectangle getXFormedBounds()

transform

public void transform(BView viewport,
                      BScalarPoint parentPos,
                      int frameCounter)

Transforms the coordinates of the drawable object to a new coordinate space, as defined by the viewport and parent pos. Subclasses should follow the following equation for tranforming relevant points etc. xformPt.x = ((localPt.x + parentPos.x + pos.x - viewport.x) * viewport.zoom ) + viewport.halfx;

Parameters:

BView - viewport - the viewport that this object is going to be drawn in

Point - parentPos - coordinates of any parent object

Overrides:

transform in class BModelElement

render

Renders the transformed coordinates of the drawable object to a Graphics2D

Parameters:

Graphics2D - g2 - the place to render the object to.

Overrides:

render in class BModelElement

newInstance

public BDrawable newInstance()

Creates and returns a new instance of the BDrawable object

Returns:

a new instance of this BDrawable object.

Overrides:

newInstance in class BModelElement

Returns:

boolean - true on success, false on failure.

Overrides:

save in class BModelElement

updateBounds
