Class VerificationBase<Events, Arguments>

Typed Event Emitter class which can act as a Base Model for all our model and communication events. This makes it much easier for us to distinguish between events, as we now need to properly type this, so that our events are not stringly-based and prone to silly typos.

Type Parameters

Events extends string
Arguments extends ListenerMap<Events | VerificationEvent>

Hierarchy

TypedEventEmitter<Events | VerificationEvent, Arguments, VerificationEventHandlerMap>
- VerificationBase

Constructors

constructor

new VerificationBase<Events, Arguments>(channel: IVerificationChannel, baseApis: MatrixClient, userId: string, deviceId: string, startEvent: null | MatrixEvent, request: VerificationRequest<IVerificationChannel>): VerificationBase<Events, Arguments>
Base class for verification methods.

Once a verifier object is created, the verification can be started by calling the verify() method, which will return a promise that will resolve when the verification is completed, or reject if it could not complete.

Subclasses must have a NAME class property.
Type Parameters
- Events extends string
- Arguments extends ListenerMap<Cancel | Events>
Parameters
- channel: IVerificationChannel
  
  the verification channel to send verification messages over. TODO: Channel types
- baseApis: MatrixClient
  
  base matrix api interface
- userId: string
  
  the user ID that is being verified
- deviceId: string
  
  the device ID that is being verified
- startEvent: null | MatrixEvent
  
  the m.key.verification.start event that initiated this verification, if any
- request: VerificationRequest<IVerificationChannel>
  
  the key verification request object related to this verification, if any
Returns VerificationBase<Events, Arguments>
