Check if this is a valid file for this IOServiceProvider. You must make this method thread safe, ie dont keep any state.

Parameters:

raf - RandomAccessFile

Returns:

true if valid.

public void open(RandomAccessFile raf,
                 NetcdfFile ncfile,
                 CancelTask cancelTask)
          throws java.io.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.

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:

java.io.IOException - if read error

makeVariable

public Variable makeVariable(NetcdfFile ncfile,
                             int datatype,
                             java.lang.String shortName,
