Comparing Class Hierarchy Relationships
The comparator methods (<
,>
, etc.) can be useful for a lot of things. In Ruby, they can be used to compare classes in order to understand how they relate to one another on the class hierarchy.
The <
operator will tell you if there is a subclass relationship. The >
operator will tell you if there is an ancestor relationship. When nil
results, it means the two classes do not have a direct relationship.
There are a few more of these types of operators on the Module class.
