Function: list ListUnique(list lAll);
Given a list of elements, strips out any duplicates in that list, and returns the de-duped list.
See also: Lists
<lsl>
list ListUnique( list lAll ) {
integer i; list lFiltered = llList2List(lAll, 0, 0); integer iAll = llGetListLength( lAll ); for (i = 1; i < iAll; ++i) { if ( llListFindList(lFiltered, llList2List(lAll, i, i) ) == -1 ) { lFiltered += llList2List(lAll, i, i); } } return lFiltered;
}
</lsl>
Example:
list mylist = ListUnique(["A", "A", "B", "C", "C", "B"])
would return the list:
["A", "B", "C"]
