Method Detail

getSAXParserFactory

public static javax.xml.parsers.SAXParserFactory getSAXParserFactory()

Returns the SAXParserFactory used to create SAXParser instances.

Returns:

The SAXParserFactory (never null).

setSAXParserFactory

public static void setSAXParserFactory(javax.xml.parsers.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).

readPieDatasetFromXML

public static PieDataset readPieDatasetFromXML(java.io.File file)
                                        throws java.io.IOException

Reads a PieDataset from an XML file.

Parameters:

file - the file (null not permitted).

Returns:

A dataset.

Throws:

java.io.IOException - if there is a problem reading the file.
