Class Methods
sort_byte
static method sort_byte : void ($array : byte[], $comparator : Comparator::Int, $offset : int = 0, $length : int = -1);
Sorts the range of the elements of byte $array in-place.
The sorted range is from $offset to the position proceeded by $length.
If the length is less than 0, the length to the end of the string is calculated from the length of the array and the offset.
The Comparator::Int comparator is used to compare each element.
Exceptions:
$array must be defined.
$offset must be greater than or equal to 0.
$comparator must be defined.
$offset + length must be less than or equal to the length of $elements.
sort_byte_asc
