Using some setters, without setting all needed properties in the constructor(s) public final class Person { // example of a bad immutability private final String name; private final String surname; public Person(String name) { this.name = name; } public String ge...
You can call a Clojure function from Java code by looking up the function and invoking it: IFn times = Clojure.var("clojure.core", "*"); times.invoke(2, 2); This looks up the * function from the clojure.core namespace and invokes it with the arguments 2 & 2.
class Message DEFAULT_MESSAGE = "Hello, world" def speak(message = nil) if message puts message else puts DEFAULT_MESSAGE end end end The constant DEFAULT_MESSAGE can be changed with the following code: Message::DEFAULT_MESSAGE = "Hullo, wo...
A lambda closure is created when a lambda expression references the variables of an enclosing scope (global or local). The rules for doing this are the same as those for inline methods and anonymous classes. Local variables from an enclosing scope that are used within a lambda have to be final. Wit...
Classes are vital aspects of OOP. A class is like the "blueprint" of an object. An object has the properties of a class, but the characteristics are not defined within the class itself. As each object can be different, they define their own characteristics. Public Class Person End Class ...
A Property procedure is a series of statement that retrieves or modifies a custom property on a module. There are three types of property accessors: A Get procedure that returns the value of a property. A Let procedure that assigns a (non-Object) value to an object. A Set procedure that assign...
Any public Sub, Function, or Property inside a class module can be called by preceding the call with an object reference: Object.Procedure In a DateRange class, a Sub could be used to add a number of days to the end date: Public Sub AddDays(ByVal NoDays As Integer) mEndDate = mEndDate + No...
This is an example of a package-info.java file that binds an XML namespace to a serializable Java class. This should be placed in the same package as the Java classes that should be serialized using the namespace. /** * A package containing serializable classes. */ @XmlSchema ( xmlns = ...
This time we are going to declare a class decorator that will add some metadata to a class when we applied to it: function addMetadata(target: any) { // Add some metadata target.__customMetadata = { someKey: "someValue" }; // Return target ret...
We can wrap a class decorator with another function to allow customization: function addMetadata(metadata: any) { return function log(target: any) { // Add metadata target.__customMetadata = metadata; // Return target return target; ...
The most common way is to apply the extension via Config. Example: # File: mysite/_config/config.yml Member: extensions: - MyMemberExtension The extensions config variable is of type "array", so you can add multiple extensions like this: # File: mysite/_config/config.yml Mem...
Orthogonal to the JRE versus JDK dichotomy, there are two types of Java release that are widely available: The Oracle Hotspot releases are the ones that you download from the Oracle download sites. The OpenJDK releases are the ones that are built (typically by third-party providers) from the Ope...
Assume you want to delegate to a class but you do not want to provide the delegated-to class in the constructor parameter. Instead, you want to construct it privately, making the constructor caller unaware of it. At first this might seem impossible because class delegation allows to delegate only to...
Typed holes can make it easier to define functions, through an interactive process. Say you want to define a class instance Foo Bar (for your custom Bar type, in order to use it with some polymorphic library function that requires a Foo instance). You would now traditionally look up the documentati...
You can create ACL by using Phalcon\Acl\Adapter\Memory class: $acl = new Phalcon\Acl\Adapter\Memory(); By default phalcon allows action to resource which has not been defined, to change this you can use: $acl->setDefaultAction(Phalcon\Acl::DENY); Roles can be added in two ways - using Pha...
You can allow role to access some action on resource by: $acl->allow('Administrator', 'products', 'create'); You can deny role to access some action on resource by: $acl->deny('Customer', 'categories', 'create'); You can check if role is allowed to some action on resource by using: $a...
You can add also add some more logic which has to be checked to your ACL using anonymous functions. They will be executed when using Phalcon\Acl\Adapter\Memory::allow() or Phalcon\Acl\Adapter\Memory::deny(), if they will return true, they role will be allowed to access certain action on resource. $...
es = Elasticsearch(hosts=hosts, sniff_on_start=True, sniff_on_connection_fail=True, sniffer_timeout=60, sniff_timeout=10, retry_on_timeout=True)
Create a Security class to run your ACL logic. <?php namespace Plugins; use Phalcon\Events\Event; use Phalcon\Mvc\Dispatcher; use Phalcon\Acl; use Phalcon\Acl\Role; use Phalcon\Acl\Resource; use Phalcon\Acl\Adapter\Memory as AclList; class Security extends \Phalcon\Mvc\User\Plugin ...
