    • retain

      A Boolean value that determines whether to set the RETAIN flag when the message is published.

      Setting the RETAIN flag causes the message to be retained and sent to new subscribers to the topic.

      Valid values: true | false

      Default value: false

      Parameters:
      retain - A Boolean value that determines whether to set the RETAIN flag when the message is published.

      Default value: false

      Returns:
      Returns a reference to this object so that method calls can be chained together.
    • payload

      PublishRequest.Builder payload(SdkBytes payload)

      The message body. MQTT accepts text, binary, and empty (null) message payloads.

      Publishing an empty (null) payload with retain = true deletes the retained message identified by topic from Amazon Web Services IoT Core.

      Parameters:
      payload - The message body. MQTT accepts text, binary, and empty (null) message payloads.

      Publishing an empty (null) payload with retain = true deletes the retained message identified by topic from Amazon Web Services IoT Core.

      Returns:
      Returns a reference to this object so that method calls can be chained together.
    • userProperties

      PublishRequest.Builder userProperties(String userProperties)

      A JSON string that contains an array of JSON objects. If you don’t use Amazon Web Services SDK or CLI, you must encode the JSON string to base64 format before adding it to the HTTP header. userProperties is an HTTP header value in the API.

      The following example userProperties parameter is a JSON string which represents two User Properties. Note that it needs to be base64-encoded:

      [{"deviceName": "alpha"}, {"deviceCnt": "45"}]

      Parameters:
      userProperties - A JSON string that contains an array of JSON objects. If you don’t use Amazon Web Services SDK or CLI, you must encode the JSON string to base64 format before adding it to the HTTP header. userProperties is an HTTP header value in the API.

      The following example userProperties parameter is a JSON string which represents two User Properties. Note that it needs to be base64-encoded:

      [{"deviceName": "alpha"}, {"deviceCnt": "45"}]

      Returns:
      Returns a reference to this object so that method calls can be chained together.
    • payloadFormatIndicator

      PublishRequest.Builder payloadFormatIndicator(String payloadFormatIndicator)

      An Enum string value that indicates whether the payload is formatted as UTF-8. payloadFormatIndicator is an HTTP header value in the API.

      Parameters:
      payloadFormatIndicator - An Enum string value that indicates whether the payload is formatted as UTF-8. payloadFormatIndicator is an HTTP header value in the API.
      Returns:
      Returns a reference to this object so that method calls can be chained together.

    • correlationData

      PublishRequest.Builder correlationData(String correlationData)

      The base64-encoded binary data used by the sender of the request message to identify which request the response message is for when it's received. correlationData is an HTTP header value in the API.

      Parameters:
      correlationData - The base64-encoded binary data used by the sender of the request message to identify which request the response message is for when it's received. correlationData is an HTTP header value in the API.
      Returns:
