                ZeroInstallImplementation

An implementation where all the information comes from Zero Install.

Since: 0.28

Instance Methods
 
__init__(self, feed, id, local_path)
id can be a local path (string starting with /) or a manifest hash (eg "sha1=XXX")		 source code
 
add_download_source(self, url, size, extract, start_offset=0, type=None, dest=None)
Add a download source.		 source code
 
set_arch(self, arch) source code
bool
is_available(self, stores)
Is this Implementation available locally? (a local implementation, an installed distribution package, or a cached ZeroInstallImplementation)		 source code

Inherited from Implementation: __cmp__, __eq__, __hash__, __le__, __repr__, __str__, get_stability, get_version

Inherited from object: __delattr__, __format__, __getattribute__, __new__, __reduce__, __reduce_ex__, __setattr__, __sizeof__, __subclasshook__

  dependencies = property(lambda self: dict([(x.interface, x) fo...
  arch = property(lambda self: _join_arch(self.os, self.machine)...

Inherited from Implementation: main, os

Instance Variables
[str] digests
a list of "algorith=value" or "algorith_value" strings (since 0.45)

Inherited from Implementation: bindings, commands, download_sources, feed, id, langs, local_path, metadata, released, requires, requires_root_install, upstream_stability, user_stability, version

Properties

Inherited from object: __class__
