Function dependencies (dependencies)

Last updated on May 25, 2023

The structure is used to describe device models and defines dependencies of functions. A dependency is when one function will only be available if another one is in a certain state.

For example, colored lamps of certain models may work in two modes: colour mode and white light mode. Based on the mode chosen by the user, the set of available functions shall change:

• In case of the colour mode, a light colour change function appears.
• In case of the white light mode, the light colour change function must be blocked.

Field	Type	Mandatory?	Description
dependencies	map<string, object>	✔︎	Contains pairs of values: the dependent function and the function defining its availability
func_name	string	✔︎	Dependent device function means a function with its availability changing, depending on the state of another function. List of functions (see Device functions)
key	string	✔︎	The function that determines the availability of the dependent function. List of functions (see Device functions)
values	object	✔︎	The values of the key function at which the dependencies function becomes available (see Device function value (value))

{
    "dependencies": {
        "func_name": {
            "key": string,
            "value": [
                {
                    "type": string,
                    "type_value": object
                },
                {
                    // ...
                }
            ]
        },
        {
            // ...
        }
    }
}

Function dependency description example

The example describes the dependency of the function light_colour (lighting colour) from the function light_mode (operation mode): the device's colour light can only be changed if it is switched to the colour mode.

{
    "dependencies": {
        "light_colour": {
        "key": "light_mode",
            "value": [
                {
                    "type": "ENUM",
                    "enum_value": "colour"
                }
            ]
        }
    }
}
