Hey all,
I just try to implement a life search on a datagrid. I was doing this
with the dgtext property. However this turns out to be too slow on
elder machines if there are many records (30k +) Now I am trying to
instead of setting the dgtext, to work with the dgdata. This could
speed up the whole process quite a lot, as the data would not need to
be turned into an array again by the data grid. Problem: arrays can
not be filtered. So what I would like to do is find the quickest
script that simulates array filtering in n dimensions if at any rate
possible. My clumsy first try looks like this. This only "filters" the
second level yet, so turning this into a function for n-levels deep
would be ideal. :)
on mouseUp
local testarray,tprocess,test
repeat with i=1 to 30000
put any item of "meier,müller,john,doe" into testarray[i]["name"]
end repeat
answer the number of lines of the keys of testarray
put the millisecs into test
put the keys of testarray into tprocess
repeat for each line theLine in tprocess
if testarray[theline]["name"]="john" then
delete variable testarray[theline]
end if
end repeat
answer the number of lines of the keys of testarray&cr&the
millisecs-test
end mouseUp
This runs in 31 ms on my machine (Intel MacBook first gen, 2.16 GHz).
I would like to have this quicker if possible. Also I´d like the
runtime on your machines, especially Macs pre Intel era.
Any thoughts highly appreciated.
All the best,
