Inspectopedia Help

Overly complex anonymous class

Reports anonymous inner classes whose total complexity exceeds the specified maximum.

The total complexity of a class is the sum of cyclomatic complexities of all the methods and initializers the class declares. Inherited methods and initializers are not counted toward the total complexity.

Anonymous classes should have very low complexity otherwise they are hard to understand and should be promoted to become named inner classes.
