instance method

Kernel#class

() -> ::Class

obj.class → class

# File tmp/rubies/ruby-4.0.0/kernel.rb, line 18
def class
  Primitive.attr! :leaf
  Primitive.cexpr! 'rb_obj_class_must(self)'
end

Returns the class of obj. This method must always be called with an explicit receiver, as class is also a reserved word in Ruby.

Example

1.class      #=> Integer
self.class   #=> Object
