progressChanged
Description copied from interface:ProgressListener
Called when progress has changed, such as additional bytes transferred, transfer failed, etc. The execution of the callback of this listener is managed bySDKProgressPublisher
. Implementation of this interface should never block.If the implementation follows the best practice and doesn't block, it should then extends from
SyncProgressListener
.Note any exception thrown by the listener will get ignored. Should there be need to capture any such exception, you may consider wrapping the listener with
ProgressListener.ExceptionReporter.wrap(ProgressListener)
.- Specified by:
progressChanged
in interfaceProgressListener
