Associated objects are useful when you want to add functionality to existing classes which requires holding state. For example, adding a activity indicator to every UIView: Objective-C Implementation #import <objc/runtime.h> static char ActivityIndicatorKey; @implementation UIView (Ac...

Integral type ranges ( IntRange , LongRange , CharRange ) have an extra feature: they can be iterated over. The compiler takes care of converting this analogously to Java's indexed for-loop, without extra overhead for (i in 1..4) print(i) // prints "1234" for (i in 4..1) print(i) // pri...

if you want to iterate over numbers in reverse order? It's simple. You can use the downTo() function defined in the standard library for (i in 4 downTo 1) print(i) // prints "4321"

Is it possible to iterate over numbers with arbitrary step, not equal to 1? Sure, the step() function will help you for (i in 1..4 step 2) print(i) // prints "13" for (i in 4 downTo 1 step 2) print(i) // prints "42"

To create a range which does not include its end element, you can use the until function: for (i in 1 until 10) { // i in [1, 10), 10 is excluded println(i) }

By default structures are padded in C. If you want to avoid this behaviour, you have to explicitly request it. Under GCC it's __attribute__((__packed__)). Consider this example on a 64-bit machine: struct foo { char *p; /* 8 bytes */ char c; /* 1 byte */ long x; /* 8 bytes */ ...

Like other value types, GUID also has a nullable type which can take null value. Declaration : Guid? myGuidVar = null; This is particularly useful when retrieving data from the data base when there is a possibility that value from a table is NULL.

const foop = { get value() {}, set value(v) {} }; it('can spy on getter', () => { spyOnProperty(foop, 'value', 'get').and.returnValue(1); expect(foop.value).toBe(1); }); it('and on setters', () => { const spiez = spyOnProperty(foop, 'value', 'set'); foop.v...

Dim rng As New Random() This declares an instance of the Random class called rng. In this case, the current time at the point where the object is created is used to calculate the seed. This is the most common usage, but has its own problems as we shall see later in the remarks Instead of allowin...

The following example declares a new instance of the Random class and then uses the method .Next to generate the next number in the sequence of pseudo-random numbers. Dim rnd As New Random Dim x As Integer x = rnd.Next The last line above will generate the next pseudo-random number and assign ...
