Function: integer ListXequY(list lx, list ly);
Answers the question: is list X identical to list Y?
Returns the number 1 if true, 0 if false
Note: requires also the function ListXnotY .
The opposite function is ListXneqY .
See also: Lists
integer ListXequY(list lx, list ly)
{
if(lx == ly)
return ListXnotY(lx,ly) == [];
return FALSE;
}
Example:
list l1 = ["a","b","c", 1,2,3];
list l2 = ["a",1,"b",3,"c",3];
integer ListXequY(list lx, list ly)
{
return ( (llGetListLength(lx) == llGetListLength(ly) ) & ( ListXnotY(lx, ly) == [] ) );
}
list ListXnotY(list lx, list ly) {// return elements in X list that are not in Y list
list lz;
integer i = llGetListLength(lx);
while(i--)
if ( !~llListFindList(ly,llList2List(lx,i,i)) )
lz += llList2List(lx,i,i);
return lz;
}
default{
state_entry() {
llSay(0, "Are we the same lists? " + (string)ListXequY(l1,l2));
//will say in this example: 0 , meaning No
}
}
