Description
|
|
Packit |
d0bcc1 |
An interface whereby an object allows its backing content to be
|
|
Packit |
d0bcc1 |
streamed to clients. Typical implementors would be images or
|
|
Packit |
d0bcc1 |
icons, HTML content, or multimedia display/rendering widgets.
|
|
Packit |
d0bcc1 |
Negotiation of content type is allowed. Clients may examine the
|
|
Packit |
d0bcc1 |
backing data and transform, convert, or parse the content in order
|
|
Packit |
d0bcc1 |
to present it in an alternate form to end-users.
|
|
Packit |
d0bcc1 |
The AtkStreamableContent interface is particularly useful for
|
|
Packit |
d0bcc1 |
saving, printing, or post-processing entire documents, or for
|
|
Packit |
d0bcc1 |
persisting alternate views of a document. If document content
|
|
Packit |
d0bcc1 |
itself is being serialized, stored, or converted, then use of the
|
|
Packit |
d0bcc1 |
AtkStreamableContent interface can help address performance
|
|
Packit |
d0bcc1 |
issues. Unlike most ATK interfaces, this interface is not strongly
|
|
Packit |
d0bcc1 |
tied to the current user-agent view of the a particular document,
|
|
Packit |
d0bcc1 |
but may in some cases give access to the underlying model data.

d0bcc1 |
Get a string representing a URI in IETF standard format
|
|
Packit |
d0bcc1 |
(see http://www.ietf.org/rfc/rfc2396.txt) from which the object's content
|
|
Packit |
d0bcc1 |
may be streamed in the specified mime-type, if one is available.
|
|
Packit |
d0bcc1 |
If mime_type is NULL, the URI for the default (and possibly only) mime-type is
|
|
Packit |
d0bcc1 |
returned.
|
|
Packit |
d0bcc1 |
Note that it is possible for get_uri to return NULL but for
|
|
Packit |
d0bcc1 |
get_stream to work nonetheless, since not all GIOChannels connect to URIs.
