There are two types of function alias rules:
Use the same New command to create a new rule of either type. Depending on the alias type, different fields appear on the Reference and Generated Output tabs.
Complete and test the function rule itself before defining a function alias rule that references it.
You cannot define an alias for a function rule
that returns a complex Java type (that is, a type other than a
Java.lang.String
type or a primitive type such as
int
).
Java alias function rules are useful for functions that managers or less technical developers may use frequently in report definition rules, decision tree rules, when condition rules, Declare Expression rules, and constraints rules.
SQL alias function rules, defined in the Embed-UserFunction class, support the development of Report Definition rules. When executed, such rules create SQL statement fragments, not Java code fragments.
Alias function rules are instances of the Rule-Alias-Function class. They belong to the Technical category.
