The SAXParserFactory (never null).

setSAXParserFactory

public static void setSAXParserFactory(SAXParserFactory f)

Sets the SAXParserFactory that will be used to create SAXParser instances. You would only call this method if you wish to configure a new factory because the default does not meet requirements.

Parameters:

f - the new factory (null not permitted).

Reads a PieDataset from an XML file.

Parameters:

file - the file (null not permitted).

Returns:

A dataset.

Throws:
