What does the hierarchy in a class define in terms of rule application?

The hierarchy in a class defines the search process for rules in the system. In Pega, the class structure is integral to how rules are organized and accessed. When a request for a rule is made, Pega uses the class hierarchy to determine where to look for that particular rule, starting from the most specific class and moving up through the hierarchy until it finds the applicable rule. This ensures that the most relevant and specific rules are applied first, allowing for a robust and flexible rule resolution process. This is crucial for maintaining the integrity and efficiency of case management in Pega applications, as it allows for the reuse of rules and promotes better organization within the system.
