- Specified by:
getInterfaces
in interfaceIType
- Returns:
- If this is a class, returns a list of all the interfaces this type implements. Similarly, if this is an interface, returns a list of all the interfaces this type extends. In any case, returns an empty list if this type neither implements nor extends interfaces.
-
getSupertype
