public List<S3ObjectSummary> getObjectSummaries() {
        return objectSummaries;
    }
Gets the list of object summaries describing the objects stored in the
S3 bucket. Listings for large buckets can be
truncated for performance reasons.  Always check the
{@link ObjectListing#isTruncated()} method to see if the returned
listing is complete or if additional calls are needed to get
more results. Callers might need to make
additional calls to
{@link AmazonS3#listNextBatchOfObjects(ObjectListing)} to get
additional results.

@return A list of the object summaries describing the objects stored in
        the S3 bucket.
