Help Fastmap -> Hashmap

[Gam3Master]

Hello cheaters.

 

I'm trying to adapt some things on aCis and as you know it uses java 8 and instead FastMap it needs HashMap and istead FastList it needs ArrayList.

 

So everytime I replace imports I have some methods which HashMap/ArrayList doesn't have or have another method .for example

What are similar methods for these in HashMap? or how can I change it?

 

Thanks in advance.

Use merge or compute methods for first cases. You can replace the whole for loop content for merge (!containsKey part included)

entries.merge(vote, 1, (oldValue, one) -> oldValue + one);

About max and result, simply = 0. It iterates over whole map to find values anyway...

If you actually understand what a map and a list is then you can pretty much do it yourself.

If I understand I wouldn't ask a question  :happyforever:

FastMap.Entry head()

Returns the head entry of this map.

FastMap.Entry getEntry(java.lang.Object key)

Returns the entry with the specified key.

 

Its pretty clear i think.

Thanks for response!

 

Sorry for dumb question one more but the final result must be

 temp = null;

 it's pointless. It's the goal of a GC to handle object deletion by itself. Otherwise yup, try and see.

Thanks understood. 

 

Thats the case if HashMap is <Integer, Integer> but what if its <L2PcInstance>?

If that would be a problem, there would have OutOfMemoryException everywhere (or at least cycles would be shorter and shorter and shorter) on aCis.

 

WeakHashMap and WeakReference exist, but if your GC runs while you retrieve your list, you can end with funny results depending how you gonna use it.

Thanks for help :)
