About predefined functions
A function is a reusable piece of code that extends the behavior of a rule. Many predefined functions are available by default in the System Library.
This section describes the predefined functions in the Central Designer application. The description of each function includes:
- Purpose of the function.
- Syntax, including parameters.
- Name, description, and data type of each parameter.
- Description of what the function returns.
- Notes about how the function works.
