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

org.jets3t.service.S3Service.listObjects()
Lists the objects in a bucket.
This method can be performed by anonymous services. @param bucket the bucket whose contents will be listed. This must be a valid S3Bucket object that is non-null and contains a name. @return the set of objects contained in a bucket. @throws S3ServiceException

        // List the object contents of each bucket.
        for (int b = 0; b < buckets.length; b++) {
            System.out.println("Bucket '" + buckets[b].getName() + "' contains:");
            
            // List the objects in this bucket.
            S3Object[] objects = s3Service.listObjects(buckets[b]);


            // Print out each object's key and size.
            for (int o = 0; o < objects.length; o++) {
                System.out.println(" " + objects[o].getKey() + " (" + objects[o].getContentLength() + " bytes)");
            }
