Modern Array SortBy

SortBy

Sorts an Array in place by your comparer; equal elements may change places.

Syntax

SortBy( a, less )

Notes

• introsort, ascending, by a comparer

Examples

#import "std/containers"
using containers

dim v as Array( of int32 )
v.Push( 5 ) : v.Push( 1 ) : v.Push( 4 )

'' A caller-supplied strict '<'. Reverse it for descending order:
SortBy( v, function( byref x as int32, byref y as int32 ) as boolean
    return x > y
end function )

for i as int32 = 0 to v.Count - 1
    print v[ i ];
next
print                    '' 5 4 1

'' The comparison may capture, because it is taken as a generic rather
'' than as a procedure pointer -- a capturing lambda is a closure object
