Parameters

consumer

The consumer object that will perform the operation.

groupId

The Sparkplug group ID.

The value represents a Sparkplug group ID, or a filter for Sparkplug group IDs. It must be a string with valid UTF-8 characters except for the reserved character '/' (forward slash). Characters '+' (plus) and '#' are filters, and can only be used when they are the single character in the string.

The value of this parameter cannot be null (Nothing in Visual Basic).

edgeNodeId

The Sparkplug edge node ID.

The value represents a Sparkplug edge node ID, or a filter for Sparkplug edge node IDs. It must be a string with valid UTF-8 characters except for the reserved character '/' (forward slash). Characters '+' (plus) and '#' are filters, and can only be used when they are the single character in the string.

The value of this parameter cannot be null (Nothing in Visual Basic).

deviceId

The Sparkplug device ID.

The value of this parameter cannot be null (Nothing in Visual Basic).

callback

The callback to invoke for the notification.

The value of this parameter can be null (Nothing in Visual Basic).

This is an extension method (info: C#, VB.NET). In languages that have support for extensions methods (such as C# and VB.NET), you can use the extension method as if it were a regular method on the object that is its first parameter. In other languages (such as with Python.NET), you will call the extension as a static method, and pass it the object on which it acts as its first parameter.
