◆ sortDescending() [3/4]

list<auto> Qore::sortDescending	(	list< auto >	l,
		string	func
	)

Performs an unstable sort in descending order and returns the new list; accepts the name of a function to use to sort complex data types or to give a special sort order.

Code Flags:: CONSTANT, DEPRECATED

Parameters

l	the list to sort
func	the name of a function accessible in the current scope that accepts 2 arguments of the data type in the list; the function must return -1, 0, or 1 if the first is less than the second, if the first and second are equal, or if the first is greater than the second, respectively

Returns: the sorted list

◆ sortDescending() [4/4]

list<auto> Qore::sortDescending	(	list< auto >	l,
		code	f
	)

Performs an unstable sort in descending order and returns the new list; accepts a call reference or a closure to use to sort complex data types or to give a special sort order.

Code Flags:: RET_VALUE_ONLY, DEPRECATED

Parameters

l	the list to sort
f	a call reference or a closure that accepts 2 arguments of the data type in the list; the code must return -1, 0, or 1 if the first is less than the second, if the first and second are equal, or if the first is greater than the second, respectively

Returns: the sorted list

◆ sortDescendingStable() [1/4]

auto Qore::sortDescendingStable ( auto arg )

This function variant does nothing at all; it is only included for backwards-compatibility with qore prior to version 0.8.0 for functions that would ignore type errors in arguments.

Code Flags:: NOOP, DEPRECATED

◆ sortDescendingStable() [2/4]

list<auto> Qore::sortDescendingStable ( list< auto > l )

Performs a stable sort in descending order and returns the new list.

This variant will only sort basic data types

Code Flags:: CONSTANT, DEPRECATED

Example:: list<auto> nl = sortDescendingStable(l);

Parameters

l	the list to sort

Returns: the sorted list

Parameters

l	the list to sort
func	the name of a function accessible in the current scope that accepts 2 arguments of the data type in the list; the function must return -1, 0, or 1 if the first is less than the second, if the first and second are equal, or if the first is greater than the second, respectively
