Method: Module#instance_methods

Defined in:
class.c

#instance_methods(include_super = true) ⇒ Array

Returns an array containing the names of the public and protected instance methods in the receiver. For a module, these are the public and protected methods; for a class, they are the instance (not singleton) methods. If the optional parameter is false, the methods of any ancestors are not included.

module A
  def method1()  end
end
class B
  include A
  def method2()  end
end
class C < B
  def method3()  end
end

A.instance_methods(false)                   #=> [:method1]
B.instance_methods(false)                   #=> [:method2]
B.instance_methods(true).include?(:method1) #=> true
C.instance_methods(false)                   #=> [:method3]
C.instance_methods.include?(:method2)       #=> true

Note that method visibility changes in the current class, as well as aliases, are considered as methods of the current class by this method:

class C < B
  alias method4 method2
  protected :method2
end
C.instance_methods(false).sort               #=> [:method2, :method3, :method4]

Returns:
