public class Expression

extends RuleComponent

An expression is a String containing either a primary expression term, such as a constant or a variable, or an advanced expression, with multiple terms and operators.

The Form property tells how it should be edited. Depending on the application, Form may be selected by the end user or fixed by the application.

FORM_SINGLE_TERM means that the expression is to be chosen from an option list, which may be either a constraint list, or a list of items from the data model. The "Show" properties can be set to create appropriate option lists from the data model.

FORM_LITERAL means that the Literal property will be used to contain a literal.

FORM_ADVANCED means that getAdvancedExpression() will be called to set and edit the expression. The validate() methods validate that the expression is syntactically and semantically correct for the context in which it is used.
