Examples of com.amazonaws.services.s3.model.ObjectListing

com.amazonaws.services.s3.model.ObjectListing
Contains the results of listing the objects in an Amazon S3 bucket. This includes a list of {@link S3ObjectSummary} objects describing the objects stored inthe bucket, a list of common prefixes if a delimiter was specified in the request, information describing if this is a complete or partial listing, and the original request parameters. @see AmazonS3#listObjects(String,String) @see AmazonS3#listObjects(ListObjectsRequest) @see AmazonS3#listNextBatchOfObjects(ObjectListing)
