Method Detail

isValidFile

public boolean isValidFile(ucar.unidata.io.RandomAccessFile raf)
                    throws IOException

Checks whether raf is a valid file NetCDF-4 file. Actually, it checks whether it is a valid HDF-5 file of any type. Furthermore, it checks whether the NetCDF C library is available on the system. If both conditions are satisfied, this method returns true; otherwise it returns false.

Parameters:

raf - a file on disk.

Returns:

true if raf is a valid HDF-5 file and the NetCDF C library is available.

Throws:

IOException - if an I/O error occurs.
