Re: Colormap, `createEnd' not implemented ... [Re: your mail]

I wasn't sure if someone had already replied to this, my
mail is sometimes slow.  Anyway...

Pietro,

   createEnd phase..."

Did you mean that you were going to eliminate the call to
`createEnd'?  If that's what you meant then I don't think
that's the best solution.

I think the only reason you get the "`createEnd' not
implemented by protocol" warning is because the Colormap
_protocol_ does not inherit the Create _protocol_.  However,
the Colormap _class_ does inherit from the CreateDrop
superclass, (just like SwarmObjects do) and therefore you
*should* call `createEnd' to complete the creation phase.

If you want to get rid of the warning then just remove the
"<Colormap>" from the declaration of the colorMap variable.
That is, instead of "id <Colormap> colorMap;" you'd only
have "id colorMap;". Of course, by doing that you'll give up
some compile-time type checking.

BTW, with the code shown below there is no need for
splitting the creation, that is you only need the following:

   colorMap = [ Colormap create: [self getZone] ];

That too would probably eliminate the warning message.

Ken.

PS: Its my understanding that now the call to `getZone' may
also be unnecessary since Swarms can now be used as Zones,
is that true?
