this.getClass(...
What is a JavaBean exactly?
...rties are inferred from the getters and setters (if there is a method X getFoo() -> the bean has a readable property called "foo"; if there is a method setFoo(X foo) -> the bean has a writeable property called "foo").

Returning multiple objects in an R function [duplicate]
... way to handle this is to return a list object. So if you have an integer foo and a vector of strings bar in your function, you could create a list that combines these items:

What __init__ and self do on Python?
...:
def __init__(self):
self.x = 'Hello'
def method_a(self, foo):
