Overview

Package axeventwrapper provides a Go wrapper around the axevent C library, facilitating the integration and manipulation of event systems within Axis devices.

Important: 

This package relies on CGo for integration with the axevent C library and the GLib library, necessitating a running GMainLoop for proper operation.

func (axEventKeyValueSet *AXEventKeyValueSet) MarkAsData(key string, namespace *string) error

Mark a key in the AXEventKeyValueSet as data. A data key is a key that represents the state of what the event represents. E.g. an event declaration that represents an I/O port should have a key marked as data which represents the state, high or low, of the port. Please note that although it is possible to mark more than one key as data, only events with one and only one data key can be used to trigger actions.

The key that represents which port the event represents should be marked as source and the key which represents the state should be marked as data. Please note that although it is possible to mark more than one key as a source, only events with zero or one source keys can be used to trigger actions.
