Module#private_method_defined?

mod.private_method_defined?(symbol, inherit=true) → true or false

mod.private_method_defined?(string, inherit=true) → true or false

static VALUE
rb_mod_private_method_defined(int argc, VALUE *argv, VALUE mod)
{
    return check_definition(mod, argc, argv, METHOD_VISI_PRIVATE);
}

Returns true if the named private method is defined by mod. If inherit is set, the lookup will also search mod’s ancestors. String arguments are converted to symbols.

Example

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

A.method_defined? :method1                   #=> true
C.private_method_defined? "method1"          #=> false
C.private_method_defined? "method2"          #=> true
C.private_method_defined? "method2", true    #=> true
C.private_method_defined? "method2", false   #=> false
C.method_defined? "method2"                  #=> false
