Method Detail

printResults

public void printResults(ResultType type,
                PrintResultWriter writer)

Specified by:

printResults in interface Printable

getResultTypeName

public java.lang.String getResultTypeName()

Specified by:

getResultTypeName in interface Printable

exportBatch

public void exportBatch(ResultWriter writer)
                 throws ResultException

Description copied from interface: BatchExportable

Exports the batch state to a result writer. Everything written to the result writer has to be read in the same order in importBatch despite the keywords.

Specified by:

exportBatch in interface BatchExportable

Parameters:

writer - the result writer which preserves the state

Throws:

ResultException - if any exception occurs while writing a result to the writer

importBatch

public void importBatch(ResultReader reader)
                 throws ResultException

Description copied from interface: BatchExportable

Imports the state of a batch from the result reader. The exported results have to read in the same order as written in exportBatch despite the keywords.

Specified by:

importBatch in interface BatchExportable

Parameters:

reader - the result reader which contains the batch state

Throws:

ResultException - if any exception occurs while reading a result from the reader

handleStopTransientPhase

public void handleStopTransientPhase()

Overrides:

handleStopTransientPhase in class Statistic

computeMeasures

resetBatchStatistic

public void resetBatchStatistic()

Description copied from class: Statistic

only between batches

Specified by:
