Hi everyone,
In the application I'm working on, there is a need to have some extra
fields on a polyline. Since there's not yet a way to add extra info to
the base Polyline class, I first thought to do this by extending the
Polyline class with my own class, however then I ran into the issue of
not being able to subclass the results of fromEncoded.
So my next attempt was to wrap a polyline object in another object
which looks like a Polyline but really just hands everything over to
the polyline it contains. My current problem is that I've come across
some functions that I need to implement but which aren't documented in
the API spec (or appear to be wrong). There seems to be issues with
the following four methods:
- IPolyline.hide()
I presume this is something like:
public function hide():Boolean;
but that doesn't seem to work.
- IPolyline.isHidden()
I got this to work with this declaration:
public function isHidden():Boolean;
- IPolyline.show()
Again, I presume it's something like:
public function show():Boolean;
but that doesn't work
- IPolyline.getLength()
This seems to be documented incorrectly, the documentation says it
should be:
public function getLength(opt_radius:Number):Number;
but that doesn't work.
Note that when i say "doesn't work" i mean that I get compile errors
like:
...\EntityPolyline.as(35): col: 15 Error: Interface method getLength
in namespace com.google.maps.interfaces:IPolyline is implemented with
an incompatible signature in class ...:EntityPolyline.
public class EntityPolyline extends EventDispatcher implements
IEntityGraphic, IOverlay, IPolyline, IWrappable,
IWrappableEventDispatcher {
Does anyone know what the correct prototypes for these methods are?
Hehe also, can anyone tell me what IWrappable and
IWrappableEventDispatcher are about? I dont really understand what the
documentation means by "cross-domain event dispatching functionality".
Pretty sure my wrapper's not going to work :) but oh well - thought
i'd at least give it a go before giving up on the whole idea and
changing my code to have a controller that sits beside a real
polyline.
Cheers,
Chris
