Module#protected_method_defined?

(::interned name, ?::boolish inherit) -> bool

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

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

static VALUE
rb_mod_protected_method_defined(int argc, VALUE *argv, VALUE mod)
{
    return check_definition(mod, argc, argv, METHOD_VISI_PROTECTED);
}

Returns true if the named protected method is defined 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
  protected
  def method2()  end
end
class C < B
  include A
  def method3()  end
end

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