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 Oracle 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.
