        s - the netcdf Structure
        list - of the member variables

             throws opendap.dap.NoSuchVariableException,
                    IOException
        Description copied from class: SDStructure
        Read a value from the named dataset for this variable.
        Specified by:
        read in interface ServerMethods
        Specified by:
        read in class SDStructure
        Parameters:
        datasetName - String identifying the file or other data store from which to read a vaue for this variable.
        specialO - This Object is a goody that is used by Server implementations to deliver important, and as yet unknown, stuff to the read method. If you don't need it, make it a null.
        Returns:
        true if more data remains to be read, otherwise false. This is an abtsract method that must be implemented as part of the installation/localization of a OPeNDAP server.
        Throws:
        opendap.dap.NoSuchVariableException - When a variable can't be found.
        IOException - When there is a problem reading data.

        public void serialize​(String dataset,
                      DataOutputStream sink,
                      CEEvaluator ce,
                      Object specialO)
               throws opendap.dap.NoSuchVariableException,
                      DAP2ServerSideException,
                      IOException
        Description copied from class: SDStructure
        Server-side serialization for OPeNDAP variables (sub-classes of BaseType). This does not send the entire class as the Java Serializable interface does, rather it sends only the binary data values. Other software is responsible for sending variable type information (see DDS).

        Writes data to a DataOutputStream. This method is used on the server side of the OPeNDAP client/server connection, and possibly by GUI clients which need to download OPeNDAP data, manipulate it, and then re-save it as a binary file.

        Specified by:
        serialize in interface ServerMethods
        Overrides:
        serialize in class SDStructure
        Parameters:
        dataset - a String indicated which dataset to read from (Or something else if you so desire).
        sink - a DataOutputStream to write to.
        ce - the CEEvaluator to use in the parse process.
        specialO - This Object is a goody that is used by a Server implementations to deliver important, and as yet unknown, stuff to the read method. If you don't need it, make it a null.
        Throws:
        opendap.dap.NoSuchVariableException - When a variable cannot be found.
        DAP2ServerSideException - When there is a server error.
        IOException - thrown on any OutputStream exception.
