Interface ICentre

All Superinterfaces:

IActionable, IAssociate, IDraggable, IRecord, RecordR, RecordRW, RecordW, SortableData, StoreRecordRW

public interface ICentre
extends IAssociate, StoreRecordRW

An ICentre object is used to position the centre of one or more circular arcs. It is used by IBezier objects which are set to be arcs.

Method Summary

void	addAssociate(IAssociate a)
void	changeRadius(IXyz p, double d) Move point p on a line from p to the centre, by the given change in radius, d.
IBezier	fixBezier() If this is non-null, the centre point location is constrained to lie on the perpendicular bisector of the end-points of the Bezier object
int	index() Returns the unique index (name) of this centre point
IXyz	p() Returns the movable centre point's current location
double	radius() Returns the radius associated with this centre point.
void	radius(double r) Set the radius for this centre point.
void	removeAssociate(IAssociate a)

Method Detail

index

int index()

Returns the unique index (name) of this centre point

p

IXyz p()

Returns the movable centre point's current location

fixBezier

IBezier fixBezier()

If this is non-null, the centre point location is constrained to lie on the perpendicular bisector of the end-points of the Bezier object

radius

double radius()

Returns the radius associated with this centre point. All Beziers attached to this centre point use this radius. This allows a single centre point to be used for related arcs, such as roundabouts

radius

void radius(double r)

Set the radius for this centre point.

radius()

changeRadius

void changeRadius(IXyz p,
                  double d)

Move point p on a line from p to the centre, by the given change in radius, d. If d is positive this moves p away from the centre point, and towards the centre point if d is negative

addAssociate

void addAssociate(IAssociate a)

Internal - Not recommended for use. Public as a side-effect of implementation method

removeAssociate

void removeAssociate(IAssociate a)

Internal - Not recommended for use. Public as a side-effect of implementation method

Remove an associate object from this ICentre
