Method Detail

createSfactors

public void createSfactors()

Description copied from class: FigXSpline

default method to create the interpolation control sfactors. We use 1.0 (approximated) everywhere except for the end points.

Overrides:

createSfactors in class FigXSpline

copy

public FigObject copy()

Description copied from class: FigXSpline

build a copy of this FigXSpline.

Specified by:

copy in interface FigObject

Overrides:

copy in class FigXSpline

insertPoint

public void insertPoint(java.awt.Point wp,
                        java.awt.Point wprev)

insert a Point wp after Point wprev into the Point array. We also update our sfactors (spline control parameters) array.

Specified by:

insertPoint in interface FigObject

Overrides:

insertPoint in class FigPolyline

deletePoint

public java.awt.Point deletePoint(java.awt.Point wp)

delete a Point wp from this polyline. This function returns the index of the predecessor of the deleted point, and null for the first point. We also update our sfactors (spline control parameters) array.

Specified by:

deletePoint in interface FigObject

Overrides:

deletePoint in class FigPolyline

rebuild

public void rebuild()

Description copied from class: FigPolyline

rebuild all internal data-structures for this polyline. This method re-calculates all internal data required for fast rendering from the world-coordinate control points, attributes, and FigTrafo2D coordinate transformation data. Therefore, this method is computationally expensive and should only be called when necessary.

Specified by:

rebuild in interface FigObject

Overrides:

rebuild in class FigXSpline
