Predefined functions

Identity Manager provides a set of predefined functions that simplify the configuration of entity property expressions and scalar rules. See the Entity Type andResource Type topics for additional information.

Unlike C# expressions, Identity Manager's predefined functions do not need any prefix. They can be used as such. See the C# utility functions topic for additional information.

Examples​

The following example shows two predefined functions. The first function normalizes the HR_Person FirstName. The other one converts the end date into a UTC date and adds 1440 minutes.

Code attributes enclosed with <> need to be replaced with a custom value before entering the script in the command line.


    <ScalarRule Property="CFirstName" Binding="HR_Person:FirstName" Expression="Simplify" Policy="Default" />
    <ScalarRule Property="CEndDate" Binding="HR_Person:EndDate" Expression="ParseLocalDateThenAddMinutes:Romance Standard Time|dd/MM/yyyy|1440" Policy="Default" />

The following table summarizes existing predefined functions:
