Function Alias rules — Completing the Create, Save As, or Specialization form

Updated on August 10, 2022

Records can be created in various ways. You can add a new record to your application or copy an existing one. You can specialize existing rules by creating a copy in a specific ruleset, against a different class or (in some cases) with a set of circumstance definitions. You can copy data instances but they do not support specialization because they are not versioned.

  1. Create a function alias rule by selecting Function Alias from the Technical category.
  2. Key parts:

  3. From the Apply to field, 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.
  4. In the Identifier field, specify a name for the rule.
    Begin the name with a letter and use only letters, numbers, the ampersand character, and hyphens.
  5. The following options listed in the Additional creation options area (referred to as Quick Create options) are are optional. Selections made here can be used as a starting point for the rule you are creating:

  6. Optional: From the Alias type field, select an alias type to preset the Java function name, template and input parameters for your newly created Functional Alias rule:
    • To set the Java function name to compareTwoValues(), choose Compare two values.
    • To set the Java function name to compareTwoValues(), choose Is Property Equal and update the template to include a specified property.
    • To set the Java function name to dateIsInRange(), Choose Date within Date Range.
    • For all SQL function alias rules and for most Java function alias rules, choose Other.
  7. In the Property field, specify the property name that will be used as the {lValue} in the compareTwoValues() function.
    This field is only available when selecting an alias type of Is Property Equal To.

When searching for instances of this rule type, 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 this rule type.
