TexyObject

TexyObject is the ultimate ancestor of all instantiable classes.

TexyObject is copy of Nette\Object from Nette Framework (https://nette.org).

It defines some handful methods and enhances object core of PHP:

• access to undeclared members throws exceptions
• support for conventional properties with getters and setters
• support for event raising functionality
• ability to add new methods to class (extension methods)

Properties is a syntactic sugar which allows access public getter and setter methods as normal object variables. A property is defined by a getter method and optional setter method (no setter method means read-only property).

$val = $obj->label; // equivalent to $val = $obj->getLabel();
$obj->label = 'Nette'; // equivalent to $obj->setLabel('Nette');

Property names are case-sensitive, and they are written in the camelCaps or PascalCaps.

Event functionality is provided by declaration of property named 'on{Something}' Multiple handlers are allowed.

public $onClick; // declaration in class
$this->onClick[] = 'callback'; // attaching event handler
if (!empty($this->onClick)) ... // are there any handlers?
$this->onClick($sender, $arg); // raises the event with arguments

Adding method to class (i.e. to all instances) works similar to JavaScript prototype property. The syntax for adding a new method is:

MyClass::extensionMethod('newMethod', function (MyClass $obj, $arg, ...) { ... });
$obj = new MyClass;
$obj->newMethod($x);
