Hi,
Lets say I have about ~100.000 of MarkupContainer objects that I want to put
into a ListView or RepeatingView.
This works fine functional wise... It's rather slow though.
It boils down to:
MarkupContainer:
1309 private Component put(final Component child)
1310 {
1311 int index = children_indexOf(child);
1312 if (index == -1)
1313 {
1314 children_add(child);
1315 return null;
1316 }
1317 else
1318 {
1319 return children_set(index, child);
1320 }
1321 }
and the call to "children_indexOf(child)" where it loops over all it's
existing children and compares the id's until a match is found.
With an increasing amount of children this can get rather slow...
I though off overruling some functionality in the MarkupContainer class since
I'm sure that for this list of items the children will be unique in their id
and don't need that lookup, and overruling the "put" or "children_indexOf"
function would give me enough power to skip that performance impacting part.
But most functions have private access, leaving me nothing to control the
adding of child components to a MarkupContainer.
Does anyone else have experience with adding rather large quantities to
something like the ListView and/or RepeatingView?
Or is there another way of rendering this large amount of containers?
Thanks in advance.
Kind regards,
Marco
