      • build

        public void build​(RandomAccessFile raf,
                  Group.Builder rootGroup,

           throws IOException
        Description copied from interface: IOServiceProvider
        Open existing file, and populate it. Note that you cannot reference the NetcdfFile within this routine. This is the bridge to immutable objects that will be used exclusively in version 6.
        Specified by:
        build in interface IOServiceProvider
        Overrides:
        build in class AbstractIOServiceProvider
        Parameters:
        raf - the file to work on, it has already passed the isValidFile() test.
        rootGroup - add objects to the root group.
        cancelTask - used to monitor user cancellation; may be null.
        Throws:
        IOException - if read error

      • setValueCharset

        protected void setValueCharset​(@Nullable

                 CancelTask cancelTask)
          throws IOException
        Description copied from interface: IOServiceProvider
        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 IOServiceProvider
        Overrides:
        open in class 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

      • readData

        public Array readData​(Variable v2,

        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:
