Class Rule

java.lang.Object
  ariba.ui.meta.core.Rule

public class Rule
extends Object

A Rule defines a map of properties that should apply in the event that a set of Selectors are matched. Given a rule base (Meta) and a set of asserted values (Context) a list of matching rules can be computed (by matching their selectors against the values) and by successively (in rank / priority order) applying (merging) their property maps a set of effective properties can be computed.
