        public void open​(ucar.unidata.io.RandomAccessFile raf,
                         ucar.nc2.NetcdfFile ncfile,
                         ucar.nc2.util.CancelTask cancelTask)
                  throws IOException
        Open existing file, and populate ncfile with it. This method is only called by the NetcdfFile constructor on itself. The provided NetcdfFile object will be empty except for the location String and the IOServiceProvider associated with this NetcdfFile object.
        Specified by:
        open in interface ucar.nc2.iosp.IOServiceProvider
        Overrides:
        open in class ucar.nc2.iosp.AbstractIOServiceProvider
        Parameters:
        raf - the file to work on, it has already passed the isValidFile() test.
        ncfile - add objects to this empty NetcdfFile
        cancelTask - used to monitor user cancellation; may be null.
        Throws:
        IOException - if read error
      • addLightningGlobalAttributes

        protected void addLightningGlobalAttributes​(ucar.nc2.NetcdfFile ncfile)
        Add the global attributes.
        Overrides:
        addLightningGlobalAttributes in class AbstractLightningIOSP
        Parameters:
        ncfile - the file to add to
      • readData

        public ucar.ma2.Array readData​(ucar.nc2.Variable v2,
                                       ucar.ma2.Section section)
                                throws IOException
        Read data from a top level Variable and return a memory resident Array. This Array has the same element type as the Variable, and the requested shape.
        Parameters:
        v2 - a top-level Variable
        section - the section of data to read. There must be a Range for each Dimension in the variable, in order. Note: no nulls allowed. IOSP may not modify.
        Returns:
        the requested data in a memory-resident Array
        Throws:
        IOException - if read error
