[JASS] Hashtable in Game Cache?

[Bribe]

Is it possible to save a hashtable into the Game Cache so as to not need a global for it? If so, how can I do this?

As per usual, reputation given to helpful sir's and the unlikely madam's.

I'm pretty sure you can't save hashtables in game cache.

Storing a hashtable in Game Cache? Never heard of that, in fact, I don't think it's even possible.

 

[Thanathos]

Well the answer is definitely no because the only things you can store in a gamecache are integers, reals, strings, booleans and units (there is neither a StoreGamecache nor a StoreHandle native for that). But its possible to store a hashtable inside a hashtable, though.

But why uses gamecaches when we have hashtables ? Hashtables are the improved version of the gamcache. They are only 2-times slower than arrays and unlike gamecaches they use integers as keys, so they don´t cause a string leak.

Also, using a global is much faster than receiving it from a gamecache (or even a hashtable, for that matter). The only real way to save a hashtable to a gamecache is probably something like this:

scope Lulu initializer Initialization
globals
    gamecache gc = InitGameCache("myCache.w3v")
    hashtable whee = InitHashtable()    
endglobals
function Initialization takes nothing returns nothing
    call StoreInteger(gc,"Data","Hashtable",GetHandleId(whee))    
endfunction
endscope

scope WhenINeedIt
function I2Hashtable takes integer id returns hashtable
    call SaveFogStateHandle(whee,0,0,ConvertFogState(id))
    return LoadHashtableHandle(whee,0,0)
endfunction

function MeNoUseGlobalHashtable takes nothing returns nothing
    local integer id = GetStoredInteger(gc,"Data","Hashtable")
    local hashtable h = I2Hashtable(id)
    call SaveUnitHandle(h,0,0,GetTriggerUnit())
    set h = null
endfunction
endscope

But I haven't tested that (I wonder if it even works), and obviously it is impractical, lol.

Still, you are limited in using specific values. I can't for example store a sound, right?

 

[Bribe]

Wait, gamecache needs a global variable, too? Forget it, that's lame

Yeah, gamecaches are pretty limited. There are still ways via storing strings of them and always the H2I(I2H()) method (shown above) but it is slow, and usually only needed in rare cases. (shouldn't be needed much though since hashtables are out)

Wait, gamecache needs a global variable, too? Forget it, that's lame

Yeah. Either way you'll end up using a global, but nothing really wrong with that. =)

Is there a bj_ variable in blizzard.j already assigned to a hashtable like bj_lastCreatedHash or something? I'd like to know what it's called, if it does exist.

EDIT: never mind, a google search turned up some results for bj_lastCreatedHashtable

 

[Pharaoh_]

GetLastCreatedHashtable(). I don't know if bj_ will work.

 

[Bribe]

I don't see the need to call back to blizzard.j if it only returns the variable declared in blizzard.j

I've seen bj_blahBlah used all kinds of times outside of the context of blizzard.j without incident...

True, but, when I tried it, it kept bringing up some errors.
