- classinterfaceToFind
- interface to find- Returns:
- type arguments of the interface
-
findParameterizedTypes
Search for the given interface or class within the root's class/interface hierarchy. If the searched for class/interface is a generic return an array of real types that fill it out.- Parameters:
root
- root classsearchedFor
- searched class- Returns:
- for generic class/interface returns array of real types
