By implementing Phalcon\Acl\RoleAware or Phalcon\Acl\ResourceAware you can use them as objects in Phalcon\Acl\Adapter\Memory::isAllowed(). // Create our class which will be used as roleName class UserRole implements Phalcon\Acl\RoleAware { protected $id; protected $roleName; publ...

\m : Beginning of a word. \M : End of a word. \y : Word boundary. \Y : a point that is not a word boundary. \Z : matches end of data. Documentation: re_syntax

First, make sure your app can be backed up in AndroidManifest.xml, i.e. android:allowBackup is not false. Backup command: adb -s <device_id> backup -noapk <sample.package.id> Create a tar with dd command: dd if=backup.ab bs=1 skip=24 | python -c "import zlib,sys;sys.stdout.wri...

The autocomplete feature in the Google Places API for Android provides place predictions to user. While user types in the search box, autocomplete shows places according to user's queries. AutoCompleteActivity.java private TextView txtSelectedPlaceName; @Override protected void onCreate(@Nulla...

When accessing a non-static member of an object through a pointer to member, if the object does not actually contain the member denoted by the pointer, the behavior is undefined. (Such a pointer to member can be obtained through static_cast.) struct Base { int x; }; struct Derived : Base { int y; ...

The following snippet replaces all Attributes called PreviousAttribute by an Attribute called ReplacementAttribute for an entire solution. The sample manually searches the Syntax tree and replaces all affected nodes. static async Task<bool> ModifySolution(string solutionPath) { ...

The following snippet replaces all Attributes called "PreviousAttribute" by an Attribute called "ReplacementAttribute" for an entire solution. The sample manually uses a SyntaxRewriter to exchange the attributes. /// <summary> /// The CSharpSyntaxRewriter allows to rewrit...

Function calls as f(a) always imply a sequence point between the evaluation of the arguments and the designator (here f and a) and the actual call. If two such calls are unsequenced, the two function calls are indeterminately sequenced, that is, one is executed before the other, and order is unspeci...

Basics A Queue is a collection for holding elements prior to processing. Queues typically, but not necessarily, order elements in a FIFO (first-in-first-out) manner. Head of the queue is the element that would be removed by a call to remove or poll. In a FIFO queue, all new elements are inserted a...

SourceCookifier parses the current source code for such components as class, function, and variable names and displays them in a tree view at a side panel. Navigation among these members is possible by double-clicking on the component name. The plugin supports a number of languages and customization...

There are no build-in methods for intersection and difference in Sets, but you can still achieve that but converting them to arrays, filtering, and converting back to Sets: var set1 = new Set([1, 2, 3, 4]), set2 = new Set([3, 4, 5, 6]); const intersection = new Set(Array.from(set1).filter(x...

If you want to add a Drawable be shown during the load, you can add a placeholder: Glide.with(context) .load(yourUrl) .placeholder(R.drawable.placeholder) .into(imageView); If you want a Drawable to be shown if the load fails for any reason: Glide.with(context) .load(yourUrl...

View loading In a test for a view controller you want sometimes to trigger the execution of loadView() or viewDidLoad(). This can be done by accessing the view. Let's say you have view controller instance in your test called sut (system under test), then the code would look like this: XCTAssertNot...

This is a mistake that causes real confusion for Java beginners, at least the first time that they do it. Instead of writing this: if (feeling == HAPPY) System.out.println("Smile"); else System.out.println("Frown"); they accidentally write this: if (feeling == HAP...

C++11 A unary operator that determines whether the evaluation of its operand can propagate an exception. Note that the bodies of called functions are not examined, so noexcept can yield false negatives. The operand is not evaluated. #include <iostream> #include <stdexcept> void f...

Below is example of service decorator, overriding null date returned by service. angular.module('app', []) .config(function($provide) { $provide.decorator('myService', function($delegate) { $delegate.getDate = function() { // override with actual date object return new Date(...

To enable resource shrinking, set the shrinkResources property to true in your build.gradle file. android { ... buildTypes { release { minifyEnabled true shrinkResources true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'p...

All libraries come with resources that are not necessary useful to your application. For example Google Play Services comes with translations for languages your own application don’t even support. You can configure the build.gradle file to specify which resource you want to keep. For example: de...

This example is about replacing a List element while ensuring that the replacement element is at the same position as the element that is replaced. This can be done using these methods: set(int index, T type) int indexOf(T type) Consider an ArrayList containing the elements "Program sta...

You can use built-in functions to run PHP processes as forks. This is the most simple way to achieve parallel work if you don't need your threads to talk to each other. This allows you to put time intensive tasks (like uploading a file to another server or sending an email) to another thread so you...
