Detailed Description

allows non-local actors to subscribe on the local addresses of a supervisor.

Member Function Documentation

activate()

void rotor::plugin::foreigners_support_plugin_t::activate ( actor_base_t *  actor )

overridevirtualnoexcept

invoked by actor upon initialization.

It it responsible for setting up reactions and further installation, e.g. messages subscriptions and may calling back actor's configuration (which can be postponed).

Before the activate is invoked, the plugin is in PREINIT phase, after the activate is called, the plugin is in INITIALIZING phase. This might be useful for early/late (double) plugin configuration in actor.

Reimplemented from rotor::plugin::plugin_base_t.

deactivate()

void rotor::plugin::foreigners_support_plugin_t::deactivate ( )

overridevirtualnoexcept

deactivates plugin from an actor

The method can be intercepted by descendants to do not deactivate too early, and called when needed.

The plugin_base_t implementation unsubscribes from all plugin subscriptions and when no subscription left commits deactivation to an actor.

Reimplemented from rotor::plugin::plugin_base_t.

identity()

const std::type_index & rotor::plugin::foreigners_support_plugin_t::identity ( ) const

overridevirtualnoexcept

returns pointer, which uniquely identifiess plugin type

Implements rotor::plugin::plugin_base_t.
