"Sort" provides sorting functions. The sorting algorithm is a stable merge sort.
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 $elements.
sort_byte_asc
"method sort_byte_asc : void ($array : byte[], $offset : int = 0, $length : int = −1);"
The alias for the following code using "sort_byte"
Sort−>sort_byte($array, method : int ($a : int, $b : int) { return $a <=> $b; }, $offset, $length);
