It's possible to specify several type constraints for generics using the where clause: func doSomething<T where T: Comparable, T: Hashable>(first: T, second: T) { // Access hashable function guard first.hashValue == second.hashValue else { return } // Access compa...

Sometimes you want to switch off all previously registered listeners. //Adding a normal click handler $(document).on("click",function(){ console.log("Document Clicked 1") }); //Adding another click handler $(document).on("click",function(){ console.log(&q...

Here we give an example of ISP violation and then refactor that violation. Without talking unnecessary things let's jump into the code. ISP violation : public interface IMessage{ IList<string> ToAddress {get; set;} IList<string> BccAddresses {get; set;} string MessageBody {get; s...

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 ...

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 ...

In contrast to the other types of workspaces, the VisualStudioWorkspace, cannot be created manually. It can be accessed when building a Visual Studio extension. When inside your extension package project, go to [YourVSPackage]Package.cs file. There you can acquire the workspace in two ways: protec...

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];

This simple example will remove the service with name "visualizer": docker service rm visualizer

This example will scale the service to 4 instances: docker service scale visualizer=4 In Docker Swarm Mode we do not stop a service. We scale it down to zero: docker service scale visualizer=0
