Typedef Documentation

using gf::MessageHandler = typedef std::function<MessageStatus(Id, Message *)>

A message handler.

gf::MessageHandler is a function that can be called when a message is sent in a message handler. It can be a free function:

gf::MessageStatus onHeroPosition(gf::Id type, gf::Message *msg) {
  assert(type == HeroPosition::type);
  auto heroPosition = static_cast<HeroPosition*>(msg);

  // do something with heroPosition->position ...

  return gf::MessageStatus::Keep;
}

// ...

gf::MessageHandler handler = onHeroPosition;

It can also be a member function (which is, in fact, the most probable use case).

struct Foo {
  gf::MessageStatus onHeroPosition(gf::Id type, gf::Message *msg) {
    assert(type == HeroPosition::type);
    auto heroPosition = static_cast<HeroPosition*>(msg);

    // do something with heroPosition->position ...

    return gf::MessageStatus::Keep;
  }
};

// ...

Foo foo;
gf::MessageHandler handler = std::bind(&Foo::onHeroPosition, &foo);
