ListCompare

Summary

Function: integer ListCompare( list a, list b );

Efficiently compares two lists for equality (same contents in the same order).
Returns an integer TRUE if the lists are equal, FALSE if not.

• list	a	–	The first list to compare.
• list	b	–	The second list to compare.

Examples

<source lang="lsl2">integer r = ListCompare([1, 2.0, "3"], [1, 2.0, "3"]); // Returns TRUE integer s = ListCompare([1, 2.0, 3], [1, 2.0, "3"]); // Returns FALSE

integer t = ListCompare([], [1, 2.0, "3"]); // Returns FALSE</source>

Implementation for LSO or MONO

<source lang="lsl2"> integer ListCompare(list a, list b) {

   if (a != b)        return FALSE;    // Note: This is comparing list lengths only

   // The next line is only needed if compiling with LSO
   if (a == [])       return TRUE;     // both lists are empty (as both lists are the same length)

   return !llListFindList(a, b);  
   // As both lists are the same length, llListFindList() can only return 0 or -1 
   // Which we return as TRUE or FALSE respectively    

} </source>
