init

I have a sql script (it is just schema definition). The script is a modified version (getting rid of the bad characters h2 doesn't like) of a mysql dumb. The script runs and the schema is inserted into the h2 database, but the issue is that all of the database names are in uppercase ('xyz' gets converted to 'XYZ'). I need them to stay in lowercase because my application is looking for the lowercase (and all of the tables in the mysql db are lowercase). Why is this happening? How can I tell h2 to not do that? Is there a better way to insert schema definition into h2? This is the INT command I'm

I am trying to subclass WKWebView. When I implement my own initializer, I got this error: 'required' initializer 'init(coder:)' must be provided by subclass of 'WKWebView' Ok, that is well known that we have to implement it for subclasses of UIView. For a direct subclass of UIView it works just implementing it, but with WKWebView it does not seem so simple. I followed the Fix-it hint, and this snippet is added to the code: required @availability(*, unavailable) convenience init!(coder: NSCoder!) { fatalError("init(coder:) has not been implemented") } So I get a class like the following: import

This is a follow up to my other post Installing signal handler with Python . In short, Linux blocks all signals to PID 1 (including SIGKILL) unless Init has installed a signal handler for a particular signal; as to prevent kernel panic if someone were to send a termination signal to PID1. The issue I've been having, is it would seem that the signal module in Python doesn't install signal handlers in a way the system recognises. My Python Init script was seemingly, completely ignoring all signals as I think they were being blocked. I seem to have found a solution; using ctypes to install the

This question already has answers here : Can Super deal with multiple inheritance? (2 answers) Possible Duplicate: Can Super deal with multiple inheritance? Python inheritance? I have a class structure (below), and want the child class to call the __init__ of both parents.

I have a class Message with two attributes, name and message , and another class MessageController with two text fields, nameField and messageField . I want to make an instance of Message in MessageController , passing these two attributes as arguments. Right now, I am doing this: Message *messageIns = [[Message alloc] init]; messageIns.name = nameField; messageIns.message = MessageField; How can I pass the values at the creation of an instance? I tried to redefine init in Message.m, but I don't know how do that. -(id)init{ if((self=[super init])){ } return self; } Please help. You have to

So i want to know which is the correct way to setup a game. I learned from google to create a new SpriteKit Project and do the following setup : In GameViewController.swift clear viewDidLoad() and add all this : override func viewDidLoad() { super.viewDidLoad() let skView = self.view as! SKView let scene = GameScene(size: skView.bounds.size) scene.scaleMode =

Can anyone explain why we need to include if (self == SomeClass class) inside the +initialize method? I’ve found similar questions (listed below), but didn’t find any specific clarifications: Objective-C: init vs initialize Should +initialize/+load always start with an: if (self == [MyClass class]) guard? Everyone says that if you don’t implement/override +initialize in Subclass, then it’s going to call the parent class twice. Can anyone explain that part in particular, specifically why does it call the parent class twice? Lastly, why doesn’t it happen when we implement +initialize in the
