Cornelius Lilge updated IO-366:
-------------------------------
Remaining Estimate: 48h
Original Estimate: 48h
> Provide feedback about the progress of time consuming tasks
> -----------------------------------------------------------
>
> Key: IO-366
> URL: https://issues.apache.org/jira/browse/IO-366
> Project: Commons IO
> Issue Type: New Feature
> Components: Utilities
> Affects Versions: 2.5
> Reporter: Cornelius Lilge
> Priority: Minor
> Labels: features
> Original Estimate: 48h
> Remaining Estimate: 48h
>
> While it is easy to copy directory structures with commons-io, it is afaik
> impossible to provide user feedback about the copy progress - same applies
> for move.
> I would suggest providing alternative interfaces of all public {{copy*}} and
> {{move*}} methods that include a "ProgressListener". The ProgressListener
> would be a simple Interface like this:
> public interface ProgressListener {
> void onProgress(long currentBytes, long totalBytes);
> }
> So for example:
> {{copyToDirectory(final File src, final File destDir)}}
> would get its alter ego:
> {{copyToDirectory(final File src, final File destDir, final ProgressListener
> progressListener)}}
> To avoid implementation overhead, I suggest that all currently existing
> {{copy}} & {{move}} methods would then call the new methods with a {{null}}
> parameter for the Progress Listener.
> I did a quick & dirty proof on concept which you can view here:
> bq. https://github.com/sne11ius/commons-io/
> Please let me know what you think about it. If you like the idea, I will
> provide a cleaner implementation with comments & tests.
