void C++ When used as a function return type, the void keyword specifies that the function does not return a value. When used for a function's parameter list, void specifies that the function takes no parameters. When used in the declaration of a pointer, void specifies that the pointer is ...
Using scanf Scanf scans text read from standard input, storing successive space-separated values into successive arguments as determined by the format. It returns the number of items successfully scanned. If that is less than the number of arguments, err will report why. Newlines in the input mus...
Sometimes you need to create your own Event, one that other plugins can listen to (Vault, among other plugins, does this) and even cancel. Bukkit's Event API allows this to be possible. All you need to do is make a new class, have it extend Event, add the handlers and the attributes your event needs...
# General syntax: # grep(<pattern>, <character vector>) mystring <- c('The number 5', 'The number 8', '1 is the loneliest number', 'Company, 3 is', 'Git SSH tag is [email protected]', 'My personal site is w...
Registering blocks is done from your main mod class, or a ModBlocks class method invoked from the main mod class during preInit. Block myBlock = new CustomBlock(); string registryname = "my_block"; block.setRegistryName(registryname); block.setUnlocalizedName(block.getRegistryName().to...

To illustrate this, here is a function that has 3 different "wrong" behaviors the parameter is completely stupid: we use a user-defined expression the parameter has a typo: we use Oracle standard NO_DATA_FOUND error another, but not handled case Feel free to adapt it to your standa...
Each standard Oracle error is associated with an error number. It's important to anticipate what could go wrong in your code. Here for a connection to another database, it can be: -28000 account is locked -28001 password expired -28002 grace period -1017 wrong user / password Here is a way ...
You can un-register individual events, entire listener classes or all events registered by your plugin or even by other plugins! Un-register specific event Each event class has the getHandlerList() static method, call that and then you can use .unregister() method. PlayerInteractEvent.getHandlerL...
This example shows how to set Click EventHandlers in a Xamarin.Android RecyclerView. In Android Java, the way to set up a listener for a Click is using a onClickListener for the view that will be clicked, like this: ImageView picture = findViewById(R.id.item_picture); picture.setOnClickListener(n...
The idea behind the AdhocWorkspace is to create a workspace on the fly. var workspace = new AdhocWorkspace(); string projectName = "HelloWorldProject"; ProjectId projectId = ProjectId.CreateNewId(); VersionStamp versionStamp = VersionStamp.Create(); ProjectInfo helloWorldProject = P...
The MSBuildWorspace is built around the concept of handling MSBuild solutions (.sln files) and their respective projects (.csproj, .vbproj). Adding new projects and documents to this workspace is not supported. string solutionPath = @"C:\Path\To\Solution\Sample.sln"; MSBuildWorkspace ...
We're good to go so, we run, again from console: mkdir our_project cd our_project Now we're in the place where our code will live. To create the main archive of our project you can run Ok, but how we create the express skeleton project? It's simple: npm install -g express express-generator ...
Swift: let services = [CBUUID(string: SERVICE1_UUID), CBUUID(string: SERVICE2_UUID)] centralManager.scanForPeripherals(withServices: services, options: nil) Objective C: NSArray *services = @[[CBUUID UUIDWithString:SERVICE1_UUID], [CBUUID UUIDWithString:SERVICE2_UUID]]; [centralManager scanFo...
Swift: var centralManager:CBCentralManager! centralManager = CBCentralManager(delegate: self, queue: nil) Objective C: @property (nonatomic, strong) CBCentralManager *centralManager; centralManager = [[CBCentralManager alloc] initWithDelegate:self queue:nil];
Swift: var centralManager:CBCentralManager! centralManager = CBCentralManager(delegate: self, queue: nil, options: [CBCentralManagerOptionRestoreIdentifierKey : "com.companyname.appname.central"]) Objective C: @property (nonatomic, strong) CBCentralManager *centralManager; self....
This simple example will remove the service with name "visualizer": docker service rm visualizer

If you already have access to your Document class from your workspace (Using Workspaces) it is easy to access the root of your Syntax tree. Document document = ... // Get document from workspace or other source var syntaxRoot = await document.GetSyntaxRootAsync();
You can easily navigate the a Syntax Tree using LINQ. For example it is easy to get all the ClassDeclarationSyntax nodes (declared classes), that have a name starting with the letter A: var allClassesWithNameStartingWithA = syntaxRoot.DescendantNodes() .OfType<ClassDeclarationSyntax>()...
