ISPEventObserver interface

Package:

@microsoft/sp-core-library

Used with the SPEvent system, this interface is implemented by components that can subscribe to events.

Extends

IDisposable

Remarks

ISPEventObserver is an abstraction of the key features that a component must have in order to subscribe to a SharePoint Framework event: It must have instanceId and componentId information for diagnostics reporting, and it must have a way to notify the event system when the component is disposed, so that its handlers can be automatically removed. Other objects may implement this contract, as long as they meet these requirements.
