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
<lsl> integer ListXequY(list lx, list ly) {
return ( ListXnotY(lx, ly) == [] );
} </lsl>
Example:
<lsl> list l1 = ["a","b","c", 1,2,3]; list l2 = ["a",1,"b",3,"c",3];
integer ListXequY(list lx, list ly) {
return ( ListXnotY(lx, ly) == [] );
}
list ListXnotY(list lx, list ly) {// return elements in X list that are not in Y list
list lz = [];
integer i = 0;
integer n = llGetListLength(lx);
for (; i < n; i++)
if (llListFindList(ly,llList2List(lx,i,i)) == -1)
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
}
} </lsl>
