Method Details

__init__(self, root=None, handler=None, src=None, command=-1, config=None, requirements=None)
(Constructor)

source code 

x.__init__(...) initializes x; see help(type(x)) for signature

Parameters:
  • requirements (requirements.Requirements) - Details about the program we want to run
  • config (config.Config Note: all other arguments are deprecated (since 0launch 0.52)) - The configuration settings to use, or None to load from disk.
Overrides: object.__init__

fetcher(self)

usable_feeds(self, iface)

source code 

Generator for iface.feeds that are valid for our architecture.

Returns: generator

See Also: arch

is_stale(self, feed)

source code 

Deprecated: use IfaceCache.is_stale

get_implementation_path(self, impl)

source code 

Return the local path of impl.

Returns: str
Raises:

get_implementation(self, interface)

source code 

Get the chosen implementation.

Parameters:
  • interface (Interface)
Returns: model.Implementation
Raises:
  • SafeException - if interface has not been fetched or no implementation could be chosen.

get_cached(self, impl)

source code 

Check whether an implementation is available locally.

Parameters:
  • impl (model.Implementation)
Returns: bool

refresh_all(self, force=True)

source code 

Start downloading all feeds for all selected interfaces.

Parameters:
  • force - Whether to restart existing downloads.

get_feed_targets(self, feed)

source code 

Deprecated: use IfaceCache.get_feed_targets

download_icon(self, interface, force=False)

source code 

Download an icon for this interface and add it to the icon cache. If the interface has no icon or we are offline, do nothing.

Returns: tasks.Task
the task doing the import, or None

get_interface(self, uri)

source code 

Deprecated: use iface_cache.IfaceCache.get_interface instead

command(self)
