StateVariable

The StateVariable implements an UPnP variable with the ability to emmit changes via EventDispatcher whenever some class variable changes.

class StateVariable(upnp_service, name, implementation, instance, send_events, data_type, allowed_values)

Bases: eventdispatcher.eventdispatcher.EventDispatcher, coherence.log.LogAble

Represents a UPnP variable. It has the ability to dispatch changes whenever some class variable changes.

Changed in version 0.9.0:

• Migrated from louie/dispatcher to EventDispatcher

• Added two more class variables:

  • StateVariable.dispatch_targets

  • StateVariable.dispatch_events

• The emitted events changed:

  • Coherence.UPnP.StateVariable.changed => state_variable_changed

  • Coherence.UPnP.StateVariable.{var name}.changed => state_variable_{var name}_changed
