StreamableContentT

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 AtkStreamableContent 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 AtkStreamableContent 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.

Functions

getMimeType string getMimeType(int i): Gets the character string of the specified mime type. The first mime type is at position 0, the second at position 1, and so on.
getNMimeTypes int getNMimeTypes(): Gets the number of mime types supported by this object.
getStream IOChannel getStream(string mimeType): Gets the content in the specified mime type.
getStreamableContentStruct AtkStreamableContent* getStreamableContentStruct(bool transferOwnership): Get the main Gtk struct
getUri string getUri(string mimeType): Get a string representing a URI in IETF standard format (see http://www.ietf.org/rfc/rfc2396.txt) from which the object's content may be streamed in the specified mime-type, if one is available. If mime_type is NULL, the URI for the default (and possibly only) mime-type is returned.
