V4RB, syntax for sorting of sets.

[Ruslan Zasukhin]

Hi all,

I want discuss one point.

So let we have selection as result of Find()

    dim set as Vset

Now I add to Vtable class new method

    Sort( set, fld, Ascending ) as VSet

This method allow us to sort selection of found records by single field.
Also we must to have other function, that will allow us sort by few fields.

It can looks for example as

    Sort( set, order() as VSortPair ) as VSet


Then in REALbasic code we could do

    dim order as array  ?

    order(1) = new VSortPair( f1, kAsc )
    order(2) = new VSortPair( f3, kDesc )
    order(3) = new VSortPair( f2, kAsc )

    SortedSet = t.Sort( set, order )


Do you like such syntax?

It seems we have no other way for RB...
