fuseboxFactory.cfc

Revision 185, 6.9 kB (checked in by scorfield, 3 years ago)
Lots of tuning! Fixes #10 but breaks #30 (which I think I will just punt on). Lots of duck typing going on now to make things faster. Also far fewer calls into the writer and far fewer calls happening inside the writer itself.
