getCreateAnimation

public Animation getCreateAnimation(View view)

Description copied from class: PlaneCurveParametric

Returns an animation that shows the curve being drawn bit-by-bit.

Overrides:

getCreateAnimation in class PlaneCurveParametric

Parameters:

view - The View where the creation animation will be shown. If this is null or if it is not an instance of PlaneCurveParametric.PlaneCurveParametricView, then the return value is null.

Returns:

A creation animation for the given View of this Exhibit. The return value can be null to indicate that no creation animation is to be run.

doDraw

public void doDraw(java.awt.Graphics2D g,
                   View view,
                   Transform transform)

Draw the curve in a specified View. If the View belongs to the class PlaneCurveParametric.PlaneCurveParametricView, then only a fraction of the curve might be drawn, as specified in the View; this feature is used in the creation animation for the curve. If the View belongs to the subclass DecoratedCurve.MMOView of PlaneCurveParametricView (which is the default), then the curve can be in some other color besides the default (this happens during the create animation, when the curve is being constructed).

Overrides:

doDraw in class PlaneCurveParametric

Parameters:

g - The graphics context where the Exhibit is being drawn. It has already been cleared to the background color (assuming that drawing is being done in the usual way, as defined in the top-level View class).

view - The View that is drawing the Exhibit; this object contains other information that might be of use, such as the Display, if any, associated with the View.

transform - Contains information about the rectangular area in the xy-plane that is being drawn and about the rectangle of pixels in the graphics context where it is drawn. Note that at least for the top-level View class, transform.getX() and transform.getY() can be assumed to be zero.

getDefaultView

public View getDefaultView()

Overridden to return a view of type MMOView.

Overrides:

getDefaultView in class PlaneCurveParametric
