Hi Leo,

 

Thank you for your reply. 

I’m aware of these kind of solutions, I use them frequently allthough I have to admit that these slipped my mind here. Great solutions by the way.

 

But getting the code working is not my problem. What I’m looking for is a generic solution for some sort of inheritance mechanism( see attachment for  an example). The code-snippet is just meant to supply the BaseX-team with an basic executable example of the bare issue. I’m not even sure if it is a bug because I don’t know if it is behavior by design. But now the BaseX-team is aware of the situation.

 

Probably I should have said that the functions can be activated cyclically in stead of just recursively. Where cyclical can be interpret as indirect recursive. And in that case the solution doesn’t hold.

 

Best,

Rob

… and you do not even need the variable

 

declare %private function local:test( $i, $test) { if ( $i > 0)  then ($i, $test( $i - 1, $test)) else() } ;

local:test( 10, local:test#2)

 

Cheers

Hi,

 

The code[1] below and send as attachment generates a error message: “Static variable depends on itself: $Q{http://www.w3.org/2005/xquery-local-functions}test”.

I use these variables to refer to my private functions in my modules so I can easyly refer to them in a inheritance situation. 

It’s not a big problem for me but I was wondering if the error-triggering is justified or that it should work. 

 

[1]===========================================

declare variable $local:test := local:test#1 ;

declare %private function local:test( $i) { if ( $i > 0)  then $local:test( $i - 1) } ;

 

$local:test( 10)

===========================================

 

Kind regards,

 

Rob Stapper
