newData

public FlatField newData(Context context,
                         VirtualFlatField virtualField)

                         RemoteException,
                         IOException

Creates a VisAD FlatField object from a netCDF indicial context and a VirtualFlatField. The returned FlatField object is, actually, a FileFlatField that uses the netCDF dataset as its (read-only) backing-store.

Overrides:

newData in class DataFactory

Parameters:

context - The netCDF indicial context.

virtualField - The virtual data.

Returns:

The VisAD FileFlatField corresponding to the input.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

IOException - I/O failure.
