Constructors

Client(ApplicationContext, IMqttPubSubClient, Dictionary<string, string>?)

Construct a new instance of this client.

public Client(ApplicationContext applicationContext, IMqttPubSubClient mqttClient, Dictionary<string, string>? topicTokenMap = null)

Parameters

applicationContext ApplicationContext

The shared context for your application.

mqttClient IMqttPubSubClient

The MQTT client to use.

topicTokenMap Dictionary<string, string>

The topic token replacement map to use for all operations by default. Generally, this will include the token values for topic tokens such as "modelId" which should be the same for the duration of this client's lifetime. Note that additional topic tokens can be specified when starting the client with StartAsync(Dictionary<string, string>?, int?, CancellationToken).

InvokeAsync(byte[], CommandRequestMetadata?, Dictionary<string, string>?, TimeSpan?, CancellationToken)

Invoke a command.

public RpcCallAsync<byte[]> InvokeAsync(byte[] request, CommandRequestMetadata? requestMetadata = null, Dictionary<string, string>? additionalTopicTokenMap = null, TimeSpan? commandTimeout = null, CancellationToken cancellationToken = default)

Parameters

request byte[]

requestMetadata CommandRequestMetadata

The metadata for this command request.

additionalTopicTokenMap Dictionary<string, string>

The topic token replacement map to use in addition to the topic tokens specified in the constructor. If this map contains any keys that the topic tokens specified in the constructor also has, then values specified in this map will take precedence.

commandTimeout TimeSpan?
