class _Loader(object) |
| |
(Singleton) Manager for downloading resources
Is a generic class which provides download services
which follow VRML97 semantics (multiple-URL definitions,
with chaining to the first successful URL).
The loader will attempt to use a local cache of files
to prevent multiple downloading.

Methods defined here:
- __call__(self, url, baseURL=None)
- Load the given multi-value url and call callbacks
url -- vrml97-style url (multi-value string)
baseURL -- optional base url from which items in url will
be resolved. protofunctions.root(node).baseURI will
give you the baseURL normally used for the given node.
raises IOError on failure
returns (successfulURL, filename, open_file, headers) on success
headers will be None for local files
- __init__(self)
- Initialize the Loader
- download(self, url)
- Download the given url to local disk, return local filename
- findHandler(self, url)
- Find registered handler for the url's apparent suffix
TODO: allow for content-type operations after downloading the URL
- get(self, url)
- Retrieve the given single-value URL
url -- single-value URL, which may be a local filename
or any URL type supported by urllib
returns (baseURL, file, filename, headers)
- load(self, url, baseURL=None)
- Load the given URL as a scenegraph
url -- the URL (or list of URLs) from which to load
baseURL -- optional base URL from which to determine
relative URL values
- loadHandlers(self)
- Load all registered handlers
- loads(self, data, baseURL='resource.wrl')
- Load given raw data as a scenegraph
baseURL -- base URL from which to determine
relative URL values
