Function Documentation

FindUpdatesSink()

components::DynamicConfigUpdatesSinkBase & dynamic_config::FindUpdatesSink	(	const components::ComponentConfig &	config,
		const components::ComponentContext &	context )

Returns component to which incoming dynamic config updates should be forwarded.

Component to be used as an updates sink is determined by the updates-sink static config field. If this field is not set, then components::DynamicConfig is used as a default sink.

Warning

Can only be called from other component's constructor in a task where that constructor was called. May block and asynchronously wait for the creation of the requested component.

Note

It is illegal to use the same updates sink from several components.
