Decision Tables As Functions

Functions may be defined in decision table form as follows:

The following restrictions apply

• There MUST be a single return value (which can be a collection)
• The data type of the function is the data type of this return value.
• Input arguments should be formally declared.
• Other conditions tested that are not passed in should be documented

The arguments may be used as conditions on their own or may be combined into more complex expressions:

Example 1

Such a function may then be used in the condition (or action of another rule)

Example 2
