Module for [StreamableContent] interface mixin
Templates 2
tmplStreamableContentT()
The ATK interface which provides access to streamable content.
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
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.
Parameters
i | a gint representing the position of the mime type starting from 0 |
Returns
a gchar* representing the specified mime type; the caller
int getNMimeTypes()
Gets the number of mime types supported by this object.
Returns
a gint which is the number of mime types supported by the object.
glib.iochannel.IOChannel getStream(string mimeType)
Gets the content in the specified mime type.
Parameters
mimeType | a gchar* representing the mime type |
Returns
A #GIOChannel which contains the content in the
specified mime type.
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.
Note that it is possible for get_uri to return NULL but for get_stream to work nonetheless, since not all GIOChannels connect to URIs.
Parameters
mimeType | a gchar* representing the mime type, or NULL to request a URI for the default mime type. |
Returns
Returns a string representing a URI, or null
if no corresponding URI can be constructed.
