Enclosing class:

ProgressRowSplittable

public static interface ProgressRowSplittable.Target

Callback interface for objects that will be informed about iteration progress, and also given the opportunity to terminate iteration. Implementations should be thread-safe; there is no guarantee about what threads they may be used from.

Method Summary

Modifier and Type	Method and Description
void	done(long count) Reports that progress has finished.
void	updateCount(long count) Reports an updated figure for the progress.

Method Detail

updateCount

void updateCount(long count)
          throws IOException

Implementations may throw an IOException from this method; the exception will be thrown during iteration from the next method of this ProgressRowSplittable and thus halt its iteration.

Parameters:

count - number of iterations so far

Throws:

IOException - to interrupt execution

done

void done(long count)

Reports that progress has finished.

Parameters:

count - final number of iterations
