Passing an object to the data property when registering a component would cause all instances of the component to point to the same data. To solve this, we need to return data from a function. var CustomComponent = Vue.extend({ data: function () { return { a: 1 } } })

Interfaces and implementations (types that implement an interface) are "detached". So it is a rightful question how to check at compile-time if a type implements an interface. One way to ask the compiler to check that the type T implements the interface I is by attempting an assignment us...

A lot of the value from local JVM unit tests comes from the way you design your application. You have to design it in such a way where you can decouple your business logic from your Android Components. Here is an example of such a way using the Model-View-Presenter pattern. Lets practice this out by...

We can load components in two ways. By initialize or override $components property in Controller By using loadComponent() method in initialize() method of Controller. Way-1 It should be override loading component by AppsController.php load one or more component class UsersController extend...

It's possible to compare lists and other sequences lexicographically using comparison operators. Both operands must be of the same type. [1, 10, 100] < [2, 10, 100] # True, because 1 < 2 [1, 10, 100] < [1, 10, 100] # False, because the lists are equal [1, 10, 100] <= [1, 10, 100] #...

Using c# or vb.net code the conversion is even more simple. An output column is needed because we type can not be changed on the fly, alternative is adding an input column on forehand make it ReadWrite. Next code will fill the new column. public override void Input0_ProcessInputRow(Input0Buffer ...

Example below shows how to create a BroadcastReceiver which is able to receive BOOT_COMPLETED events. This way, you are able to start a Service or start an Activity as soon device was powered up. Also, you can use BOOT_COMPLETED events to restore your alarms since they are destroyed when device is ...

The GHC compiler has mature support for compiling with profiling annotations. Using the -prof and -fprof-auto flags when compiling will add support to your binary for profiling flags for use at runtime. Suppose we have this program: main = print (fib 30) fib n = if n < 2 then 1 else fib (n-1)...

SQL Server 2008 R2 Supported compound operators: += Add and assign -= Subtract and assign *= Multiply and assign /= Divide and assign %= Modulo and assign &= Bitwise AND and assign ^= Bitwise XOR and assign |= Bitwise OR and assign Example usage: DECLARE @test INT = 42; SET @test...

There are many compilers that support different versions of the OpenMP specification. OpenMP maintains a list here with the compiler that support it and the supported version. In general, to compile (and link) an application with OpenMP support you need only to add a compile flag and if you use the ...

For example, types for SI units have been standardized in the F# core library, in Microsoft.FSharp.Data.UnitSystems.SI. Open the appropriate sub-namespace, UnitNames or UnitSymbols, to use them. Or, if only a few SI units are required, they can be imported with type aliases: /// Seconds, the SI uni...

(.) lets us compose two functions, feeding output of one as an input to the other: (f . g) x = f (g x) For example, if we want to square the successor of an input number, we can write ((^2) . succ) 1 -- 4 There is also (<<<) which is an alias to (.). So, (+ 1) <<&lt...

Control.Category defines (>>>), which, when specialized to functions, is -- (>>>) :: Category cat => cat a b -> cat b c -> cat a c -- (>>>) :: (->) a b -> (->) b c -> (->) a c -- (>>>) :: (a -> b) -> (b -> c) -> (a -> c...

Summary: MVVM is an architectural pattern that is represented by three distinct components, the Model, View and ViewModel. In order to understand these three layers, it is necessary to briefly define each, followed by an explanation of how they work together. Model is the layer that drives the bus...

This is an simple example to create a mysql server with docker 1.- create docker-compose.yml: Note: If you want to use same container for all your projects, you should create a PATH in your HOME_PATH. If you want to create it for every project you could create a docker directory in your project. ...

You can wrap values into actions and pipe the result of one computation into another: return :: Monad m => a -> m a (>>=) :: Monad m => m a -> (a -> m b) -> m b However, the definition of a Monad doesn’t guarantee the existence of a function of type Monad m => m a -&...

When storing JSON documents in SQL Server, We need to be able to efficiently filter and sort query results on properties of the JSON documents. CREATE TABLE JsonTable ( id int identity primary key, jsonInfo nvarchar(max), CONSTRAINT [Content should be formatted as JSON] CHECK...

There are two Collections.sort() methods: One that takes a List<T> as a parameter where T must implement Comparable and override the compareTo() method that determines sort order. One that takes a List and a Comparator as the arguments, where the Comparator determines the sort order. ...

Databings are essential for working with XAML. The XAML dialect for UWP apps provides a type of binding: the {x:Bind} markup extension. Working with {Binding XXX} and {x:Bind XXX} is mostly equivalent, with the difference that the x:Bind extension works at compile time, which enables better debuggi...
