Constructor Detail

NcSDGrid

public NcSDGrid(String name,
                List<opendap.dap.BaseType> list)

Constructor.

Parameters:

name - of the Grid

list - of the variables, first data then maps

Method Detail

read

public boolean read(String datasetName,
                    Object specialO)
             throws opendap.dap.NoSuchVariableException,
                    IOException

Description copied from class: SDGrid

Read a value from the named dataset for this variable.

Specified by:

read in interface ServerMethods

Specified by:

read in class SDGrid

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.
