Shorter, faster, and just plain tidier :-)
Hmm… there’s a few reasons I’m not a fan of this pattern:
- you can’t really clearly document the handler parameters although this could
feasibly be worked around by redefining what a parameter is in your docs
Well, it's not my pattern (in fact, initially I didn't even spot that it
did this "trick" to handle a point) - so I may be the wrong one to
defend it - but here goes.
The common use case is where the parameters are any one of
- one or two points
- a rect
- one to four coords
(i.e. anywhere you are basically passing in a rectangle in the various
common flavours).
I think I've seen it in few places (presumably Geometry Engine, maybe
one of the chart libraries, etc.)
