[Mondrian] Array data type implemented?

[Julian Hyde]

I don't believe that there is any mapping from an MDX type to a Java
double[]. So, no MDX expression would ever match the signature required to
call that function.
 
But, we could add a mapping:
 
1. It would be reasonable to pass in a set of members or tuples; each would
be evaluated, and its cell value converted to a double.
 
2. MDX does not have a type for an array of scalar values. We could add one,
but it would be a lot of work. I'd rather not go there.
 
3. Someone please investigate what Microsoft does. I believe that they tend
to serialize values as strings to pass them over the COM boundary to
user-defined functions. So I think they would use SetToArray here.
 
Andreas, Can you please log a feature request.
 
Julian

Hi,

I've seen some finacial functions in Vba.java that take a doube[] array
argument, for example 

publicstaticdoublenPV(doubler, double[] cfs)

Can these functions be accessed from MDX? Has anyone an example how to pass
the double array?

Kind Regards,
Andreas
