Examples of org.jets3t.service.S3Service.listObjectsChunked()

org.jets3t.service.S3Service.listObjectsChunked()
Lists the objects in a bucket matching a prefix, chunking the results into batches of a given size, and returning each chunk separately. It is the responsility of the caller to building a complete bucket object listing by performing follow-up requests if necessary.
This method can be performed by anonymous services. @param bucketName the name of the the bucket whose contents will be listed. @param prefix only objects with a key that starts with this prefix will be listed @param maxListingLength the maximum number of objects to include in each result chunk @param priorLastKey the last object key received in a prior call to this method. The next chunk of objects listed will start with the next object in the bucket after this key name. This paramater may be null, in which case the listing will start at the beginning of the bucket's object contents. @return the set of objects contained in a bucket whose keys start with the given prefix. @throws S3ServiceException
