module AWS
class S3
# Represents the uploads in progress for a bucket.
#
# Note: After you initiate multipart upload and upload one or more
# parts, you must either complete or abort multipart upload in order
# to stop getting charged for storage of the uploaded parts. Only
# after you either complete or abort multipart upload, Amazon S3 frees
# up the parts storage and stops charging you for the parts storage.
#
# @example Finding uploads by prefix
#
# bucket.multipart_uploads.with_prefix("photos/").
# map { |upload| upload.object.key }
# # => ["photos/1.jpg", "photos/2.jpg", ...]
#
# @example Browsing with a tree interface
#
# bucket.multipart_uploads.with_prefix("photos").as_tree.
# children.select(&:branch?).map(&:prefix)
# # => ["photos/2010", "photos/2011", ...]
#
# @see Tree
