Map or hash

[slenkar]

Is there something in FreePascal that allows you to store and retrieve objects and give them keys ?
I see there is a thread called 'superfast hash' but I dont see the functions
'insert' and 'get'

There should be a hashtable in contnrs.pas

Seems like delphi doesn't have it. At least not there. Some more quick datastructures in the standard library would've been nice.

I downloaded one from here:http://www.benya.com/code/collections/hashtable.html

but when I try to retrieve an object it crashes:

this is the code im using to test the hashtable

s:=ship_array[0];
hashy.setValue('trev',s);
s:=spaceship(hashy.getValue('trev'));

but this line causes the crash:

function tHashEntry.getKey : tComparable;
begin
     result := fKey;
end;

There is ThashedStringlist. I've used it for my latest project (non-gamedev related). It's easy to use and does the job well.

Check out the unit Generics.Collections (D2009/D2010/XE).

Ah thanks. I guess I should really make the move to D2010 or XE.
