Description copied from interface: Configurable

This method is called when this configurable component needs to be reconfigured.

Specified by:

newProperties in interface Configurable

Parameters:

ps - a property sheet holding the new data

Throws:

PropertyException - if there is a problem with the properties.

getData

public abstract Data getData()
                      throws DataProcessingException

Returns the processed Data output.

Specified by:

getData in interface DataProcessor

Returns:

an Data object that has been processed by this DataProcessor

Throws:

DataProcessingException - if a data processor error occurs
