U2I vs H2I

05-15-2008, 05:44 PM	#1
Troll-Brain	JASS: function U2I takes unit u returns integer return u return 0 endfunction function H2I takes handle h returns integer return h return 0 endfunction What is the fastest solution, if i use an unit variable. For me, it should be the U2I function. and yes i know the difference should be insignificant ...

Toadcop	imo no difference... only h2i is more universal. =)

d07.RiV	First of all, what is the question?? Second, I suppose the conversion from unit to handle does not have any overhead at all.

Rising_Dusk	H2I is insignificantly faster, H2I is also significantly more universal.

O_o rly ? i think it makes no sense. cause unit is extended from handle. so handle is the main class. but well.

stupid question "stupid" answers =)

Captain Griffen	It probably has to type cast from unit to handle, which shouldn't take any time really. It's probably less than the difference between typing '1.' and '1' for a real in the WE.

Strilanc	I'm going to ahead and say there will be no difference whatsoever, except the inability to pass non-units to U2I. Both should compile to the same byte code. Of course, it depends on Blizzard handled variable types. You can usually get away with totally ignoring the type at run-time (they do check it in native calls, but there is no native call here).

Fuck me, I totally mistyped that. Yeah, H2I() would be insignificantly faster because handle is the parent data type.

Coming from the guy who preloads 6000 timers in order to speed up attaching ...

Toadcop	yes but it's the uber thread >.< it's kind a what is faster: 3+1 or 2+2 ? see yes 2+2 maybe is faster but (i don't really know) but in fact it's 0 differense. btw precached timers are also VERY save. // cause i align handle stack before creting them xD

Anyways, the reality is that functions using handle arguments in Jass all behave the same during runtime, the difference between handles only begins when calling the natives.
