Hi all, I have come across a problem that I am unsure how to get around. What I want to do is create a subclass of Scientific.IO.NetCDFFile, but despite what the docstrings say isn't really a class at all, but a function that returns some sort of data structure from the netcdf C api. I am aware of pure python implementations such as scipy.io.netcdf_file, but these seem to have internal limitations causing overflows when opening large (e.g. several gigabytes) files.
I have tried creating a class with an open NetCDFFile as a member (f). File attributes are easy enough to deal with (self.__dict__=self.f.__dict__), and I can even create callable methods such as self.dimensions which return self.f.dimensions. However, when it comes to more esoteric aspects such as multi- dimensional slicing of the variables (derived somehow from numpy.array), I am somewhat at a loss. So my question is: Is there a simple method of containing NetCDFFile in a class? If not, how can I design a class that will behave like NetCDFFile from the user perspective?
