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

initialize

public void initialize()

Initializes this DataProcessor. This is typically called after the DataProcessor has been configured.

public DataProcessor getPredecessor()

Returns the predecessor DataProcessor.

Specified by:

getPredecessor in interface DataProcessor

Returns:

the predecessor

setPredecessor

public void setPredecessor(DataProcessor predecessor)

Sets the predecessor DataProcessor. This method allows dynamic reconfiguration of the front end.

Specified by:

setPredecessor in interface DataProcessor

Parameters:

predecessor - the new predecessor of this DataProcessor
