how to sort n:m relations

[Dipl.-Ing. Werner Riegler]

hi

I wold need help how to do this:

Class AB{
Relationship A As A [ Cardinality = one, Inverse = Bs ];
Relationship B As B [ Cardinality = one, Inverse = As ];
Property SortOrder As %Integer [ InitialExpression = 1 ];
Index ...
}

Class A{
 Relationship Bs As AB [ Cardinality = many, Inverse = Campaigns ];
...
}

Class B [ ClassType = persistent, ProcedureBlock ]
{
  Relationship As As AB [ Cardinality = many, Inverse = Campaigns ];
...
}

now I have an Instance A of Class A

and I can loop through using

A.Bs.Count()
A.Bs.GetAT(x)
A.Bs.GetAT(x).B
A.Bs.GetAT(x).SortOrder

do I need a loop to walk through every entry
or is there something like an array_sort like in PHP available ?
