Method Detail

continueOnError

public boolean continueOnError(long errs,
                      long progress,
                      Object offender,
                      String mesg)

This method returns true if the data loading is to be continued upon encountering this error. Data loading is supposed to be interrupted if this method returns false

Specified by:

continueOnError in interface DataLoaderListener

Parameters:

errs - number of errors encountered so far.

progress - a long value indicating the current progress. It must be a positive integer.

offender - the object value that triggers an error condition

mesg - an optional string value describing the current progress and error condition.

getInstance

public static SimpleLogBasedDataLoaderListenerImpl getInstance(long freq)

This method returns an instance of DataLoaderListener

Parameters:

freq - frequency of progress reporting. This must be a positive integer.

getInstance

public static SimpleLogBasedDataLoaderListenerImpl getInstance(long freq,
                                               boolean continueOnError)

This method returns an instance of DataLoaderListener

Parameters:

freq - frequency of progress reporting. This must be a positive integer.

continueOnError - continue on error if this flag is set to true

progressTo

public void progressTo(long progress,
              String mesg)

This method reports the current progress.

Specified by:

progressTo in interface ProgressListener

Overrides:

progressTo in class SimpleLogBasedProgressListenerImpl

Parameters:

progress - a long value indicating the current progress. It must be a positive integer.

mesg - an optional string value describing the current progress.

reportDataLoaderFrequency

public long reportDataLoaderFrequency()

Returns a positive integer as the frequency of progress reporting.

Returns:

progress reporting frequency which must be a positive integer.
