public class BlobInfo implements Serializable
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.
Constructors
BlobInfo(BlobKey blobKey, String contentType, Date creation, String filename, long size)
public BlobInfo(BlobKey blobKey, String contentType, Date creation, String filename, long size)
BlobInfo(BlobKey blobKey, String contentType, Date creation, String filename, long size, String md5Hash)
public BlobInfo(BlobKey blobKey, String contentType, Date creation, String filename, long size, String md5Hash)
BlobInfo(BlobKey blobKey, String contentType, Date creation, String filename, long size, String md5Hash, @Nullable String gsObjectName)
public BlobInfo(BlobKey blobKey, String contentType, Date creation, String filename, long size, String md5Hash, @Nullable String gsObjectName)
Creates a BlobInfo
by providing the BlobKey and all
associated metadata. This is typically done by the API on the developer's
behalf.
