I am trying to use VisAD to display some data sets. I have the
display working, but i run into problems when I want to load a
new data set. Here are the specifics:
I have an application that displays the data, and allows for
some manipulation of the data (which is working). I would like
to allow the user to load a new data set without restarting the
application. To do this, I am trying to create a new instance
of the VisAD class in question.
EG:
visad_class_name = new visad_class();
[some code ...]
// Time to create a new instance with the new data:
visad_class_name = null; // first, i erase the old instance
(since i have static variables)
visad_class_name = new visad_class();
It compiles alright, but i get the runtime exception:
visad.TypeException: ScalarType: name already used
I have seen this exception before when i've tried to create more
than one class with the same scalar-maps (as when multiple
classes are mapping data on latitude and longitude axis). I
don't quite understand when/why this exception arises. As a
result, I'm not sure how to solve the problem.
Any information or help would be appreciated.
Thank you for your help and patience,
megan
