Returns a reference point where to attach labels; when this returns an invalidCoord then the attachment is either not done at all, or done in a specific way (like for curves, or for points) The treatment of points could also take advantage of this attachment mechanism. If this method returns a valid Coordinate, then this is interpreted as a pivot point for the label, which can still be moved relative to that point, but follows the object when the object changes. In practice a new RelativePointType is created (position of the string), this type in turn depends on the object (to get its attachPoint) and two DoubleObject that are interpreted as relative displacement (x and y) Implements Object. |
|
|
Returns a copy of this Object. The copy is an exact copy. Changes to the copy don't affect the original. Implements Object. |
|
|
Returns true if this Object is equal to rhs. This function checks whether rhs is of the same Object type, and whether it contains the same data as this Object. Implements Object. |
|
|
Returns the lowermost ObjectType that this object is an instantiation of. E.g. if you want to get a string containing the internal name of the type of an object, you can do:
tn = object.type().internalName() Implements Object. |
