Class

export Class(clsDef: ClassDefinition) : Type<any>

Provides a way for expressing ES6 classes with parameter annotations in ES5.

Basic Example

var Greeter = ng.Class({ constructor: function(name) { this.name = name; }, greet: function() { alert('Hello ' + this.name + '!'); } });

is equivalent to ES6:

class Greeter { constructor(name) { this.name = name; } greet() { alert('Hello ' + this.name + '!'); } }

or equivalent to ES5:

var Greeter = function (name) { this.name = name; } Greeter.prototype.greet = function () { alert('Hello ' + this.name + '!'); }

Example with parameter annotations

var MyService = ng.Class({ constructor: [String, [new Optional(), Service], function(name, myService) { ... }] });

is equivalent to ES6:

class MyService { constructor(name: string, @Optional() myService: Service) { ... } }

Example with inheritance

var Shape = ng.Class({ constructor: (color) { this.color = color; } }); var Square = ng.Class({ extends: Shape, constructor: function(color, size) { Shape.call(this, color); this.size = size; } });
