[Plplot-devel] RE: [Plplot-cvs] CVS update notice (plplot/examples/java)

[Geoffrey F. <fu...@ga...>]

Hi, I looked at this tonight, but I'm afraid I don't see clearly what
you are driving at.  What would you like to be able to write?  Java
has an ArrayList which may be what you're after, if I'm guessing
right.  

I have not every written back-end JNI code to extract data from an
ArrayList.  But I probably need to work through this exercise at some
point.
