Constructor Detail

SlidableOvalAnchor

public SlidableOvalAnchor()

Default constructor

SlidableOvalAnchor

public SlidableOvalAnchor(
IOvalAnchorableFigure f)

Creates default SlidableOvalAnchor with a reference points at the center of the figure

Parameters:: f - the IOvalAnchorableFigure that this anchor will be associated with

SlidableOvalAnchor

public SlidableOvalAnchor(
IOvalAnchorableFigure f,
                          
PrecisionPoint p)

Creates SlidableOvalAnchor with a specified reference points

Parameters:: f - the IOvalAnchorableFigure that this anchor will be associated with; p - the PrecisionPoint that the anchor will initially attach to.

Method Detail

getBox

protected 
Rectangle getBox()

Description copied from class: SlidableAnchor

Gets the anchors associated figure's bounding box in absolute coordinates.

Overrides:: getBox in class SlidableAnchor

Returns:: a Rectangle that is the bounding box of the owner figure in relative coordinates

getIntersectionPoints

protected 
PointList getIntersectionPoints(
Point ownReference,
                                          
Point foreignReference)

Description copied from class: BaseSlidableAnchor

Calculates intersection points of the figure and the line that passes through ownReference and foreignReference points

Overrides:: getIntersectionPoints in class BaseSlidableAnchor

Parameters:: ownReference - the reference Point on or inside the shape that is being anchored to.; foreignReference - the outside reference Point point that is the terminal end of the line formed by the two parameters.
Returns:: intersection points of the figure and the line that passes through ownReference and foreignReference points
