DummyReceiveEndpoint

Extends Endpoint

Dummy endpoints are used during construction of the endpoint mesh.

receive

dummy does nothing by intention.

isIn

Returns boolean true

isOpen

Returns boolean true

isDummy

Indicate whatever we are a dummy endpoint. Dummy endpoints are used duiring construction of the endpoint mesh.

Returns boolean true

ConnectionState

Type: Object

Endpoint

Connection endpoint.

Parameters

• name string endpoint name

• owner Object of the endpoint (service)

• options Object

  • options.didConnect Function? called after receiver is present

displayName

Name as presented for humans.

Returns string

isDefault

Indicate whatever we are a default endpoint. Default means buildin.

Returns boolean false

isDummy

Indicate whatever we are a dummy endpoint. Dummy endpoints are used duiring construction of the endpoint mesh.

Returns boolean false
