[14:50:32] trevnorris:   groundwater: there are others that are "safer", whatever that's about :P
[14:50:41] trevnorris:	 but still almost as fast
[14:51:10] trevnorris:	 groundwater: are you creating an object just to attach these objects?
[14:51:38] groundwater:	 i will be
[14:51:43] trevnorris	 flogs github
[14:52:02] groundwater:	 right now i'm actually converting between c++ / js land but that's proving to be a losing strategy
[14:52:47] groundwater:	 and i'm just playing around with various approaches to find the best fit
[14:52:59] trevnorris:	 groundwater: then the actual proper way to do this is create an ObjectTemplate, set the InternalFieldCount = 1
[14:53:21] trevnorris:	 then use SetAlignedPointerInInternalfield
[14:53:43] trevnorris:	 oy, again. SetAlignedPointerInInternalField (int index, void *value)
[14:53:53] groundwater:	 awesome
[14:54:20] trevnorris:	 yeah, use the ObjectTemplate to create your new objects, then you can store as many pointers on the object as you want
[14:54:36] groundwater:	 same question as before, is there a callback i can register for when the object is reaped by teh GC?
[14:54:43] trevnorris:	 use GetAlignedPointerFromInternalField to get the pointer out
[14:55:15] trevnorris:	 for that you need to Persistant the object you create, then set the weak callback
[14:55:24] trevnorris:	 you can see an example in master src/smalloc.cc
[14:55:34] groundwater:	 okay, yah tjfontaine showed me that example
[14:56:15] trevnorris:	 yeah, that's actually the only way to accomplish that. no performance tricks around that crap
[14:56:24] groundwater:	 thanks, this is great
