atk.StreamableContent — the ATK interface which provides access to streamable content.
class atk.StreamableContent(gobject.GInterface): |
An interface whereby an object allows its backing content to be streamed to clients. Typical implementors would be images or icons, HTML content, or multimedia display/rendering widgets.
Negotiation of content type is allowed. Clients may examine the backing data and transform, convert, or parse the content in order to present it in an alternate form to end-users.
The atk.StreamableContent
interface is particularly useful for saving, printing, or
post-processing entire documents, or for persisting alternate views of a
document. If document content itself is being serialized, stored, or
converted, then use of the atk.StreamableContent
interface can help address performance issues. Unlike most ATK
interfaces, this interface is not strongly tied to the current
user-agent view of the a particular document, but may in some cases give
access to the underlying model data.
