zeroinstall.injector.solver.DefaultSolver

Class DefaultSolver

object --+ | Solver --+ | DefaultSolver

The standard (rather naive) Zero Install solver.

Instance Methods

__init__(self, network_use, iface_cache, stores, extra_restrictions=None)

Method Details

init(self, network_use, iface_cache, stores, extra_restrictions=None)
(Constructor)

source code

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Parameters:

network_use (model.network_levels) - how much use to make of the network
iface_cache (iface_cache.IfaceCache) - a cache of feeds containing information about available versions
stores (zerostore.Stores) - a cached of implementations (affects choice when offline or when minimising network use)
extra_restrictions ({model.Interface: [model.Restriction]}) - extra restrictions on the chosen implementations

Overrides: object.__init__

solve(self, root_interface, arch)

source code

Get the best implementation of root_interface and all of its dependencies.

Parameters:

root_interface - the URI of the program to be solved
arch - the desired target architecture

Returns: bool

whether we have a viable selection

Overrides: Solver.solve
