I haven't tried it, but something like this might work from a pure rules
perpsective:
$i : Object() from sPointer[]
$j : Object() from $i // I think this will instance of, checking it's a
array and thus iterate over it
$p : Object( this == $j ) from aPointer
But as that is create a Rete evaluation tree, it won't be as efficient
as a simple for loop. But would make an interesting test.
Mark
sPointer is a int[][]; aPointer is a ArrayList. I need to find which element
in aPointer has the same value in sPointer.
If I use function, I think it the efficiency is not so good. Do you have any
other ideas?
