Update of /cvsroot/monetdb/pathfinder/compiler/core
In directory sc8-pr-cvs7.sourceforge.net:/tmp/cvs-serv2478/core
Modified Files:
Tag: XQuery_0-16
fs.brg
Log Message:
Until now, document managenment functions could not be called from
user-defined functions (`docmgmt' is not a subtype of `item*').
Similar in spririt to the `declare updating function' syntax in the
W3C Update Facility, we now have the syntax extension
declare document management function foo(...)
{
...
};
That sets the return type `docmgmt*' for the respective function.
(I have the magic ability to foresee Peter's reactions on lengthy
syntax such as `declare document management function'. Based on my
predictive abilities, I also included the short-hand `declare
docmgmt function' for Peter's convenience. ;-))
