Properties

Signals

• requestReceived()

Detailed Description

Set the topic and node properties and provide a handler function to answer requests. The handler is invoked as (request, reply) => response; it may return the response value directly, or return undefined and call reply.send(response) later for work that takes time.

Alternatively, answer declaratively without a handler: bind the response property, and each incoming request is answered with its current value. The binding may depend on on state changed in onRequestReceived.

The response is a Qtros2LifecycleMsgs::State value.

Property Documentation

response : Qtros2LifecycleMsgs::State

The declarative response. When no handler is set, each incoming request is answered immediately with the current value of this property. Bindings re-evaluate synchronously, so the expression may depend on state updated in onRequestReceived — both are already up to date when the response is sent. A callable handler takes precedence over this property.

Signal Documentation

requestReceived()

Emitted when a request arrives, before the handler is invoked.
