Function Alias rules
Completing the New or Save As form

Create a function alias rule by selecting Function Alias from the Technical category.

A function alias rule has two key parts, a class and a purpose:

Field	Description
Applies To	Select a class. Many function alias rules use @baseclass. To create an SQL function alias rule, select or enter Embed-UserFunction. Specifying any other class creates a Java function alias rule.
Rule Name	Enter a name (often called a 'purpose' in Process Commander) for the rule. Begin the name with a letter and use only alphanumeric, ampersand, and dash characters.

 

Alias Type field

For all SQL function alias rules, and for most Java function alias rules, accept the default value of Other as the alias type.

The Alias Type field is provided as a convenience when you create Java function aliases for the following functions:

Java function	Select
compareTwoValues()	Compare two values
compareTwoValues() function with the parameters pre-populated with the selected property and the “equals” operator	Is Property Equals To
dateIsInRange()	Date within Date Range

For general information on the New form, see Completing the new rule dialog box. For general information on the Save As form, see How to enter rule keys using Save As.

Rule resolution

FTTT When searching for a function alias rule, the system:

• Filters candidate rules based on a requestor's RuleSet list of RuleSets and versions
• Searches through ancestor classes in the class hierarchy for candidates when no matching rule is found in the starting class.
• Finds circumstance-qualified rules that override base rules with the same key

Time-qualified resolution features are not available for function alias rules.
