Summary
Function: list listCast( list mixedList, integer type );
Iterates through the contents of a list, producing a resulting list whose contents are cast to a single type. Please refer to llGetListEntryType() for valid types. This function is useful for converting a list to a type which is more memory efficient, or to a type that you know you are going to access a lot (in order to remove extra casting later-on).
Returns a list A list whose contents are all one type.
| • list | mixedList | – | The list to cast, its contents may be anything. | |
| • integer | type | – | One of the TYPE_* variables, see llGetListEntryType() for more details. |
Examples
Implementation
<lsl>list listCast(list mixedList, integer type) {
list result = []; integer x = mixedList != [];
if (type == TYPE_INTEGER)
while ((--x) >= 0)
result = (result = []) + [llList2Integer(mixedList, x)] + result;
else if (type == TYPE_FLOAT)
while ((--x) >= 0)
result = (result = []) + [llList2Float(mixedList, x)] + result;
else if (type == TYPE_VECTOR)
while ((--x) >= 0)
result = (result = []) + [(vector)llList2String(mixedList, x)] + result;
else if (type == TYPE_ROTATION)
while ((--x) >= 0)
result = (result = []) + [(rotation)llList2String(mixedList, x)] + result;
else if (type == TYPE_STRING)
while ((--x) >= 0)
result = (result = []) + [llList2String(mixedList, x)] + result;
else if (type == TYPE_KEY)
while ((--x) >= 0)
result = (result = []) + [llList2Key(mixedList, x)] + result;
else result = (mixedList = []) + mixedList;
return (result = mixedList = []) + result;
