Formula expressions in business rules
In formula expressions, you enter literals,
context objects, arithmetic operators, and utility functions directly
in the text field. The arithmetic operators are +, -, *, /, and %. For information about these
operators, see Arithmetic expressions in Gosu. Utility functions are defined globally
and are always available.
When you start typing, autocomplete shows you available objects, properties, and methods based on the selected Rule Context and filtered by the text you enter.
To select from available objects, press
Spacebar. Type one or
two letters to display first-level objects containing letters in that
order. Type a period after the object to select its subobjects, properties,
and methods. Type three or more letters to display objects containing
letters in that order. The letters can match objects at multiple levels
of nesting. The number of levels is defined in the BizRulesLeafSearchNumOfHops parameter
in config.xml. The default
value is 3.
For example, if you type
cont, you can choose objects
at three levels such as policyEvalContext,
policyPeriod.BillingContact,
and policyPeriod.BasedOn.ContainerId.
To access utility functions, type Util followed by a period.
The following formula expressions use literals and comparison operators:
5050 + 50"some" + "thing"
