Hi,
I have recently started using the ucar java class library and have come
across what I think might be a bug. I hope this list is the correct one for
questions of this type and has some users or developers of this package who
can help me.
I am using version 2.2 of the Java library and during testing had a problem
with the ucar.nc2.Variable class. In the following method:
Array read(int [] origin, int [] shape)
The following line calculates the last index in the required range. I think
it is doing this incorrectly when the statring point (first) is anything
other than the first element (0). The routine then crashes a line or two
later:
int last = (shape==null) ? getShape()[i] : first + shape[i] - 1;
I had to change the line to:
int last = (shape==null) ? getShape()[i] : shape[i] - 1;
This seems to make more sense since it appears that the 'last' variable
should contain the index of the last element in the array, rather than a
count of the number of elements to be read, which is what the original line
of code would suggest it is trying to do (even then I think the code would
need some attention). On the other hand this seems like a piece of bread
and butter code which is constantly used, so I am worried that I am doing
else wrong.
Has anyone come across this problem? Is there a NetCDF developer who can
help me?
Thanks
Brian
