Methods

_unregisterSub

(
  • sub
)

Defined in event/js/synthetic.js:157

Available since 3.4.0

Removes the subscription from the Notifier registry.

Parameters:

  • sub Subscription

    the subscription

detachAll

() private

Defined in event/js/synthetic.js:185

Available since 3.4.0

Used by the event system's unload cleanup process. When navigating away from the page, the event system iterates the global map of element subscriptions and detaches everything using detachAll(). Normally, the map is populated with custom events, so this object needs to at least support the detachAll method to duck type its way to cleanliness.

register

(
  • handle
)

Defined in event/js/synthetic.js:145

Available since 3.4.0

Adds a subscription from the Notifier registry.

Parameters:
