Method Detail

getBounds

Rectangle2D getBounds()

Get the bounding box of the shape used to draw this connector end.

getConnection

void getConnection(Point2D p)

Get the connection point of the end. The given point is modified with the location to which the connector should be drawn.

getOrigin

void getOrigin(Point2D p)

Get the origin of the line end. The given point is modified.

paint

void paint(Graphics2D g)

Paint the connector end. This method assumes that the graphics context is already set up with the correct paint and stroke.

setNormal

void setNormal(double angle)

Set the normal of the connector end. The argument is the angle in radians away from the origin.

setOrigin

void setOrigin(double x,
               double y)

Set the origin of the decoration.

translate

void translate(double x,
               double y)

Translate the connector end by the given amount.
