Abstract Value Members
- abstract def eventSubject: Option[String]
The origin subject of the
The origin subject of the

. For example, the entity id when the event was emitted from an entity.
- abstract def getGrpcClient[T](clientClass: Class[T], service: String): T
Get an Akka gRPC client for the given service name.
Get an Akka gRPC client for the given service name. The same client instance is shared across components in the application. The lifecycle of the client is managed by the SDK and it should not be stopped by user code.
- T
The "service" interface generated for the service by Akka gRPC
- clientClass
The class of a gRPC service generated by Akka gRPC
- service
The name of the service to connect to, either a name of another Kalix service or an external service where connection details are configured under
akka.grpc.client.[service-name]inapplication.conf.

- abstract def getTracer: Tracer
Get an OpenTelemetry tracer for the current action.
Get an OpenTelemetry tracer for the current action. This will allow for building and automatic exporting of spans.
- returns
A tracer for the current action, if tracing is configured.

- ActionCreationContext
- abstract def materializer(): Materializer
An Akka Stream materializer to use for running streams.
An Akka Stream materializer to use for running streams. Needed for example in a command handler which accepts streaming elements but returns a single async reply once all streamed elements has been consumed.

- Context
- abstract def metadata: Metadata
Get the metadata associated with this call.
Get the metadata associated with this call.
Note, this only returns call level associated metadata. For unary calls, this will be the same as the message metadata, but for streamed calls, it will contain metadata associated with the whole stream, so for example if this was a gRPC call, it will contain the HTTP headers for that gRPC call.
- returns
The call level metadata.
