Hi Rob,
What do you mean by »activating« functions? Do you want to invoke
all of the returned functions in a loop?

Hi Rob,
Glad to have you back! I have revised the inspect:functions
function;
from now on, it also returns updating functions [1].

Hi Christian,
After a period of focussing on Angular I’m back at to BaseX
;-).
I found that the inspect:functions function does not return
updating
functions. Is that by design?
I would like to be able to use the inspect:functions function for
triggering
my update function on the server side, which of course are
updating
functions
TIA for you reply,
Cheers,
Rob Stapper
Hi Christian,
one remark: the as a result of a inspect:functions() returned
updating
functions can only be activated when MIXUPDATES option is set to
true.
This is however a workaround.
Seems like a generic issue for this kind of %processing functions.
Buiding two variants for each situation, %updating and
non-%updating,
for these kind of %processing functions doesn't feel like the
optimal
solution. Maybe something to put on the agenda (just a thought)
Best,
Rob
Christian,
this is my actual dispatcher code.

declare
   %rest:path("/DB")
   %rest:POST("{$specifications}")
   %input:json("format=xquery")

   %output:method("adaptive")
   %output:indent("no")
   %updating function _:dispatch
       ( $specifications as array(*)
       )
       {
          _:response( update:apply( function( $requester      as 
xs:string
                                            , $objectType     as 
xs:string
                                            , $transaction    as 
xs:string
                                            , $specifications as array(*)
                                            )
                                            { inspect:functions()[     
namespace-uri-from-QName( function-name(.)) = $objectType
                                                                   and    
local-name-from-QName( function-name(.)) = $transaction
                                                                 ]( 
$specifications)
                                            }
                                  , $specifications
                                  )
                    )
       } ;

I want a flexible client-server configuration for prototyping. 
Performance is not an issue here.
This is what I ended up with. Pretty creative. isn't it?

So no loop, but a filter.

Hope this gives you any insight in my madness ;-)

Rob
