publicclassBlobInfoimplementsSerializable
BlobInfo contains metadata about a blob. This metadata is gathered by
parsing the HTTP headers included in the blob upload.
See Also: RFC 1867 for the specification of HTTP file uploads.
Returns the object name of this Blob, if it is stored in Google Cloud Storage,
in the form /[bucket-name]/[object-name]. Returns null if the Blob is stored
in Blobstorage.
