Detailed Description

ParameterType.PARAMETER_NOT_SET indicates that the parameter was not set (if gotten) or is uninitialized. Values are enumerated in `ParameterType.msg`.

ParameterValuePublisher publishes parameterValue values to a ROS 2 topic. Set the topic and node properties, then call publish() to send messages.

See also ParameterValueSubscriber and parameterValue.

Property Documentation

boolArrayValue : list<bool>

The boolArrayValue field value included in the next publish. Setting this property emits boolArrayValueChanged and, when autoPublish is true, requests a publish at the end of the current event-loop iteration.

boolValue : bool

The boolValue field value included in the next publish. Setting this property emits boolValueChanged and, when autoPublish is true, requests a publish at the end of the current event-loop iteration.

byteArrayValue : ArrayBuffer

The byteArrayValue field value included in the next publish. Setting this property emits byteArrayValueChanged and, when autoPublish is true, requests a publish at the end of the current event-loop iteration.

doubleArrayValue : list<double>

The doubleArrayValue field value included in the next publish. Setting this property emits doubleArrayValueChanged and, when autoPublish is true, requests a publish at the end of the current event-loop iteration.

doubleValue : double

The doubleValue field value included in the next publish. Setting this property emits doubleValueChanged and, when autoPublish is true, requests a publish at the end of the current event-loop iteration.

integerArrayValue : list<int64_t>

The integerArrayValue field value included in the next publish. Setting this property emits integerArrayValueChanged and, when autoPublish is true, requests a publish at the end of the current event-loop iteration.

integerValue : int64_t

The integerValue field value included in the next publish. Setting this property emits integerValueChanged and, when autoPublish is true, requests a publish at the end of the current event-loop iteration.

stringArrayValue : list<string>

The stringArrayValue field value included in the next publish. Setting this property emits stringArrayValueChanged and, when autoPublish is true, requests a publish at the end of the current event-loop iteration.

stringValue : string

The stringValue field value included in the next publish. Setting this property emits stringValueChanged and, when autoPublish is true, requests a publish at the end of the current event-loop iteration.

type : uint8_t

The type field value included in the next publish. Setting this property emits typeChanged and, when autoPublish is true, requests a publish at the end of the current event-loop iteration.
