getSuperGenericClass

public static Class<?> getSuperGenericClass(Class<?> c,
 int n,
 Class<?> def)

query for the nth generic type of the parent of a class. This method perform a lookup only to the direct super class (if any)

Parameters:

c - the class to be queried

n - the nth generic to be looked for

def - the default class returned when the nth generic type is not a class (for example it is a variable) or if the parent has no generics

Returns:

the Class type of the generic

findSuperGenericClass

public static Class<?> findSuperGenericClass(Class<?> c,
 int n,
 Class<?> def)

query for the nth generic type of the parent of a class. This method perform a lookup over the super classes hierarchy

Parameters:

c - the class to be queried

n - the nth generic to be looked for

def - the default class returned when the nth generic type is not a class (for example it is a variable) or if the parent has no generics

Returns:

the Class type of the generic
