Constructor Detail

PgBezierCurve

public PgBezierCurve(int aVertexDim)

Method Detail

init

public void init()

Description copied from class: PgPolygon

Initialize and reset instance variables after call to super.init().

Overrides:

init in class PgPolygon

copy

public void copy(PsObject object)

Copy instance variables by duplication, not by copying a reference.

The argument was changed from PgGeometry to PsObject since there were problems in J/Link which preferred to use PsObject#copy(PsObject) instead of PgGeometry#copy(PsObject).

Overrides:

copy in class PgPolygon

See Also:

PgPolygon.clone()

Version:

08.11.02, 1.10 revised (kp) Argument changed to PsObject from PgGeometry.

getControlPoint

public PdVector[] getControlPoint()

getNumControlPoints

public int getNumControlPoints()

setNumControlPoints

public void setNumControlPoints(int aNum)

Set number of control points. All controlPoint allocation should be done in this method.

addControlPoint

public void addControlPoint(PdVector aPoint)

setControlPoint

public void setControlPoint(int anIndex,
                            PdVector aPoint)

setNumVertices

public void setNumVertices(int aNum)

Description copied from class: PgPolygon

Adjust the number of vertices of the polygon.

Internally the number of edges are updated.

Overrides:

setNumVertices in class PgPolygon

computeVertices

public void computeVertices()

eval

public void eval(PdVector v,
                 double t)

update

public boolean update(java.lang.Object event)

Description copied from class: PgPolygon

Update the class whenever a child has changed. Method is usually invoked from the children.

Specified by:

update in interface PsUpdateIf

Overrides:

update in class PgPolygon

Parameters:

event - carries a lot of information

Returns:

true if event has been handled, otherwise false
