Throws:

VisADException - if the save fails.

save

public void save(DataImpl data,
                 boolean bigObject)
          throws VisADException

Save a big Data object to the file. If called with bigObject set to true, special measures will be taken to make sure that only the necessary parts of a Data object are loaded, so that objects too large to fit in memory have a better chance of being saved.

Parameters:

data - Data object to save

bigObject - true if this is a really big object

Throws:

VisADException - if the save fails.

setFile
