Specified by:

processorWorkFlow in interface IOProcessor

setUpProcess

public void setUpProcess()

Description copied from interface: IOProcessor

Initialise the io processor with the necessary in-memory objects and metrics

Specified by:

setUpProcess in interface IOProcessor

cleanUp

public void cleanUp()
             throws ProcessorNotInitialised

Description copied from interface: IOProcessor

Cleans up memory from unused objects after processing is finished

Specified by:

cleanUp in interface IOProcessor

Throws:

ProcessorNotInitialised

startProcessing

public void startProcessing()
                     throws ProcessorNotInitialised

Description copied from interface: IOProcessor

Process the dataset for quality assessment

Specified by:

startProcessing in interface IOProcessor

Throws:
