The following code is correct: public Sample mOboeSamples[] = { new Sample(1,1), new Sample(1,2) }; public Sample mGuitarSamples[] = { new Sample(1,1), new Sample(1,2) }; public SampleSet mSampleSet[] = { new SampleSet( "oboe", mOboeSamples ), new SampleSet( "guitar", mGuitarSamples) }; but I'd like to write ...
Hi all, I am returning to C++ after a long absence and I am stumbling a little over my understanding of the fairly well known static initialization problem. Let's say I have a simple class Vector2 as given below (note that I am aware that x and y should be private with getters and setters, these have just been omitted for brevity): cl...

Should I a) write a custom init method with my data as argument, like this? MyCustomViewControllerSubclass.m: -(id) initWithNibName: bundle: myCustomData: {...

For a class instance to work properly, some fields should be properly initialized, what's your strategy to initialize these field, what should be given through constructor, what should be given through property?

For example we declare a field as static (without a value assignment). And then write several lines of the code which generate and assign a value to...

At the moment I require that the host application calls a Register method in the application's Main method to register the handlers and various sub-systems. I...

Taking shoulda as an example, when trying to run rake test:units I get the following error: DEPRECATION...
