Parameters:

c - Class

Returns:

an array of friendly property names (String[])

listAllInterfaces

List all interfaces implemented by the given class

Parameters:

c - Class

Returns:

List of all interfaces (Class) implemented by the class

listAllSuperClasses

Returns a List of all super classes of the given class

Parameters:

c - Class

Returns:

a List of all super classes of the given class

isRunnable
