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].

Best,
Christian

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,

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 ;-)
