Hi, For those who follow this discussion and find it an interesting case, hereby an example of the problem I’m facing.
The example throws an error: Static variable depends on itself: ……
The example concerns a 3-step cyclic construct:
“BASE-TYPE.xqm” -> “SUPER-TYPE.xqm” -> “SUPER-SUPER-TYPE.xqm” ->
“BASE-TYPE.xqm”,
starting of from “test.xq”.
I need the solution to comply with four rules:
- The module-functions must be %private and may only be addressed from outside
the module through a public module-$variable. This way inheritance between
modules can simply be implemented by the use of variables.
- The internal structure of a module-function must be completely hidden for use
outside the module. So if the module-function calls another function it is not
allowed to pass this called upon function or its name in the module-function’s
parameterlist. That is why I can’t use Leo solution here.
- The 3-step cycle structure can not be changed.
- I need a generic solution.
The solution is of course that it just works; Christian is having a look at it,
but I thought it an interesting enough case to share and maybe somebody comes
up with an solution that does complies to these rules as a temporary 😉 work
around. My solution for the time being is violating my first rule.
Have fun,
Rob Stapper
PS for using the example, just extract it and copy the extracted directory in
BaseX’s src-directory. Start "test.xq” from within BaseX and it should work
