Description

Currently Listing has a S3AFileSystem instance to use its required methods thus giving listing access to all of S3AFileSystem methods. Ideal way would be to use a callback interface in Listing which can in turn call s3Afs methods thus restricting the listing to methods which are absolutely required.
