Usage
An attribute_check script belongs to an object or service and checks conditions relying on several mutually dependant attribute values.
![[Note]](images/note.png) | Note |
|---|---|
To check the value of a single attribute instead of several, mutually dependant attributes, the attribute's check script should be used instead of the attribute_check script. See the section called “Attribute check script” for checking a single attribute. |
Selector syntax

attribute_list_check_script_selector | "attribute_check" | the section called “attribute_check script” |
Input arguments
All attributes are implicitly provided as input arguments for this script. The id suffix and type of each input argument is the same as those of its respective attribute.
| Note |
|---|---|
At the time of writing, attributes of kindvariable with property setable set to all are not provided as input arguments. This limitation will probably disappear in a future version. |
Output argument
This script always has one output argument whose id is o_error and whose type is ty_error_check_attribute_list. o_error is void if all conditions are fulfilled. Otherwise it returns an error describing the first check that failed.
