public interface ObjectCountCallback {
	
Invoked when the PackWriter has counted the objects to be written to pack. 
 An ObjectCountCallback can use this information to decide whether the PackWriter.writePack(ProgressMonitor, ProgressMonitor, OutputStream) operation should be aborted. 

This callback will be called exactly once.

Params:
  • objectCount – 
           the count of the objects.
Throws:
