I get a deprecation warning with @Override, but I was unable to find the proper way to do it. Am I meant to add override before the method like this? >override public void startThread(Thread t, int pri) { > ... >} Am I meant to wrap the entire method in override { } like this? > override { > public void startThread(Thread t, int pri) { > ... > } > } Both of them compile, so I'm wondering which to use. Is override {} supposed to be for adding multiple methods inside to avoid writing override before each method, or is putting override in front of the method without brackets just wrong? |

What error message exactly are you getting and on what code?
Both styles you put there should work equally well.

I had no error on the examples I posted, only when using @Override previously. It just says to use override attribute instead of @Override
source\game\client.d(8,20): Deprecation: implicitly overriding base class method game.GameWindow.startThread with game.client.Client.startThread deprecated; add 'override' attribute
source\game\client.d(7,3): Error: undefined identifier 'Override'

Yeah, that just means use the override keyword on the method. There is no @Override thing, it is a plain lowercase keyword.

Override is an undefined symbol in your code. @Override is user defined attribute (UDA) syntax. The programmer is responsible for defining the semantics of user defined attributes. Ali |

Unlike in Java, D's override indicator doesn't look like an annotation, it's just a keyword placed before a method along the same lines as "static" or "public" or "protected".
