Hashtable tutorial somewhere?

[krainert]

I've been pointed to the Table library, and I've stumbled upon gamecashe, but what I really need is a hashtable. The thing is, without auto-completion and a function list (this issue) it's really tedious to figure out how to get things done. Anybody know any tutorials?

Yeah, but that's GUI. I need something that can act as a reference for the JASS hashtable functions.

 

[tooltiperror]

hashtable hash=InitHashtable();

function onInit()
{
  call SaveInteger(hash, 1, 1, 25235235)
  call BJDebugMsg(I2S(LoadInteger(hash, 1, 1)))
}

Thanks. Which data types are supported ("Save"/"Load"+DataType)? Also how do I use a non-integer as key? As I recall, GUI handled that using handle ID's.

 

[tooltiperror]

// Using a unit as a key
integer key = GetHandleId(unit)
SaveInteger(key, 0, 1233);

Everything except for code can be saved.

Hashtable API

Just to clarify on TTE's answer, you must use an integer as the key. However, all handles (though you should only use agents) can be converted to integers using [ljass]GetHandleId[/ljass].

You can do stuff not supported here with typecasting. i.e. you can save a [LJASS]gamestate[/LJASS] I believe.

Thanks. GetHandleID and the API should do.
One last question: Is there a way to check whether a parent key exists within a hashtable?
