Ds\Deque::sortedReturns a sorted copy

˵��

public Ds\Deque::sorted ([ callable $comparator ] ) : Ds\Deque

Returns a sorted copy, using an optional comparator function.

comparator

callback ( mixed $a, mixed $b ) : int
Caution

Returning non-integer values from the comparison function, such as float, will result in an internal cast to integer of the callback's return value. So values such as 0.99 and 0.1 will both be cast to an integer value of 0, which will compare such values as equal.

����ֵ

Returns a sorted copy of the deque.
