objectIsSubclassOfClass

public static boolean objectIsSubclassOfClass(Object pObject,
                                              Class pClass)

Returns true if the object passed in is a subclass of the class passed in. Returns false if the object is exactly the same class as the object passed in, or if the object is part of a different class hierarchy.

objectIsMemberOfClass

public static boolean objectIsMemberOfClass(Object pObject,
                                            Class pClass)

Returns true if the object passed in is an instance of the class passed in. The object must EXACTLY be the same class as the class passed in.

objectIsKindOfClass

public static boolean objectIsKindOfClass(Object pObject,
                                          Class pClass)

Return true if class of object, or any superclass thereof, is the same as the class argument.

public static URL determineWhereClassIsLoadedFrom(Class cls)

Parameters:

cls -

Returns:
