Sort provides sorting functions. The sorting algorithm is a stable merge sort.
Class Methods
sort_byte
static method sort_byte : void ($array : byte[], $offset : int, $length : int, $comparator : Comparator::Byte)Sort the range of the elements of byte array in-place.
The sorted range is from the offset to the offset + the length - 1.
The Comparator::Byte comparator is used to compare each element.
The array must be defined. Otherwise an exception will be thrown.
The offset must be greater than or equal to 0. Otherwise an exception will be thrown.
The length must be greater than or equal to 0. Otherwise an exception will be thrown.
The comparator must be defined. Otherwise an exception will be thrown.
The offset + length must be less than or equal to the length of the elements. Otherwise an exception will be thrown.
