ruby - Is there a way to avoid definition of a method with a certain name? -


is there way avoid (raise error when attempted) definition of method name, example foo#bar? (a usecase when foo#bar defined, , want avoid method being overridden, irrelevant question.) assuming like:

class foo   prohibit_definition :bar end  ... # later in code  class foo   def bar     ...   end end # => error: `foo#bar' cannot defined

maybe can catch callback in method_added() of module class , check method name , delete added method if not meet criteria. can raise error.

not want close enough think.

class class   def method_added(method_name)     if method_name == :bar         remove_method :bar         puts "#{method_name} cannot added #{self}"   end end

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
