public class XFI_filter_member_network_selection extends XFFunction
The function has parameters dimension QName and Member QName for start exploring for more members in the same domain. Surprisingly the function does not considers the concept QName which is supposed to make USE OF THE DIMENSION through an hypercube. It looks like the authors of the functions specification took a very syntactical approach to the dimensions specification rather than an object model approach in which an object is declared once and used multiple times. Certainly, the Dimensions Specification was written with the idea of being able to redefine a dimension members each time a dimension is used in a concept and this function is ignoring this capability.

XFFunctionThis method is called after all references to functions and variables have been resolved to the declaration of the function or variable, and after all type checking has been done.
optimize in class XFFunctionvisitor - an expression visitorcontextItemType - the static type of "." at the point where this expression is invoked.
The parameter is set to null if it is known statically that the context item will be undefined.
If the type of the context item is not known statically, the argument is set to
