+@class Class

+
+L.Class powers the OOP facilities of Leaflet and is used to create almost all of the Leaflet classes documented here.
+
+In addition to implementing a simple classical inheritance model, it introduces several special properties for convenient code organization — options, includes and statics.
+
+
+@example
+
+```js
+var MyClass = L.Class.extend({
+initialize: function (greeter) {
+	this.greeter = greeter;
+	// class constructor
+},
+
+greet: function (name) {
+	alert(this.greeter + ', ' + name)
+	}
+});
+
+// create instance of MyClass, passing "Hello" to the constructor
+var a = new MyClass("Hello");
+
+// call greet method, alerting "Hello, World"
+a.greet("World");
+```
+
+@section Class Factories
+@example
+
+You may have noticed that Leaflet objects are created without using
+the `new` keyword. This is achieved by complementing each class with a
+lowercase factory method:
+
+```js
+new L.Map('map'); // becomes:
+L.map('map');
+```
+
+The factories are implemented very easily, and you can do this for your own classes:
+
+```js
+L.map = function (id, options) {
+    return new L.Map(id, options);
+};
+```
+@section Inheritance
+@example
+
+You use L.Class.extend to define new classes, but you can use the same method on any class to inherit from it:
+
+```js
+var MyChildClass = MyClass.extend({
+    // ... new properties and methods
+});
+```
+
+This will create a class that inherits all methods and properties of the parent class (through a proper prototype chain), adding or overriding the ones you pass to extend. It will also properly react to instanceof:
+
+```js
+var a = new MyChildClass();
+a instanceof MyChildClass; // true
+a instanceof MyClass; // true
+```
+
+You can call parent methods (including constructor) from corresponding child ones (as you do with super calls in other languages) by accessing parent class prototype and using JavaScript's call or apply:
+
+```
+var MyChildClass = MyClass.extend({
+    initialize: function () {
+        MyClass.prototype.initialize.call(this, "Yo");
+    },
+
+    greet: function (name) {
+        MyClass.prototype.greet.call(this, 'bro ' + name + '!');
+    }
+});
+
+var a = new MyChildClass();
+a.greet('Jason'); // alerts "Yo, bro Jason!"
+```
+
+@section Options
+@example
+
+`options` is a special property that unlike other objects that you pass
+to `extend` will be merged with the parent one instead of overriding it
+completely, which makes managing configuration of objects and default
+values convenient:
+
+```js
+var MyClass = L.Class.extend({
+    options: {
+        myOption1: 'foo',
+        myOption2: 'bar'
+    }
+});
+
+var MyChildClass = MyClass.extend({
+    options: {
+        myOption1: 'baz',
+        myOption3: 5
+    }
+});
+
+var a = new MyChildClass();
+a.options.myOption1; // 'baz'
+a.options.myOption2; // 'bar'
+a.options.myOption3; // 5
+```
+
+There's also [`L.Util.setOptions`](#util-setoptions), a method for
+conveniently merging options passed to constructor with the defaults
+defines in the class:
+
+```js
+var MyClass = L.Class.extend({
+    options: {
+        foo: 'bar',
+        bla: 5
+    },
+
+    initialize: function (options) {
+        L.Util.setOptions(this, options);
+        ...
+    }
+});
+
+var a = new MyClass({bla: 10});
+a.options; // {foo: 'bar', bla: 10}
+```
+
+Note that the options object allows any keys, not just
+the options defined by the class and its base classes.
+This means you can use the options object to store
+application specific information, as long as you avoid
+keys that are already used by the class in question.
+
+@section Includes
+@example
+
+`includes` is a special class property that merges all specified objects into the class (such objects are called mixins).
+
+```js
+ var MyMixin = {
+    foo: function () { ... },
+    bar: 5
+};
+
+var MyClass = L.Class.extend({
+    includes: MyMixin
+});
+
+var a = new MyClass();
+a.foo();
+```
+
+You can also do such includes in runtime with the `include` method:
+
+```js
+MyClass.include(MyMixin);
+```
+
+`statics` is just a convenience property that injects specified object properties as the static properties of the class, useful for defining constants:
+
+```js
+var MyClass = L.Class.extend({
+    statics: {
+        FOO: 'bar',
+        BLA: 5
+    }
+});
+
+MyClass.FOO; // 'bar'
+```
+
+
+@section Constructor hooks
+@example
+
+If you're a plugin developer, you often need to add additional initialization code to existing classes (e.g. editing hooks for `L.Polyline`). Leaflet comes with a way to do it easily using the `addInitHook` method:
+
+```js
+MyClass.addInitHook(function () {
+    // ... do something in constructor additionally
+    // e.g. add event listeners, set custom properties etc.
+});
+```
+
+You can also use the following shortcut when you just need to make one additional method call:
+
+```js
+MyClass.addInitHook('methodName', arg1, arg2, …);
+```

+Whenever a class inheriting from `Evented` fires an event, a listener function

+The object that originally fired the event. For non-propagated events, this will
+be the same as the `target`.

+@class Interactive layer
+@inherits Layer
+
+Some `Layer`s can be made interactive - when the user interacts
+with such a layer, mouse events like `click` and `mouseover` can be handled.
+Use the [event handling methods](#evented-method) to handle these events.
+
+@option interactive: Boolean = true
+If `false`, the layer will not emit mouse events and will act as a part of the underlying map.
+
+@option bubblingMouseEvents: Boolean = true
+When `true`, a mouse event on this layer will trigger the same event on the map
+(unless [`L.DomEvent.stopPropagation`](#domevent-stoppropagation) is used).
+
+@section Mouse events
+
+@event click: MouseEvent
+Fired when the user clicks (or taps) the layer.
+
+@event dblclick: MouseEvent
+Fired when the user double-clicks (or double-taps) the layer.
+
+@event mousedown: MouseEvent
+Fired when the user pushes the mouse button on the layer.
+
+@event mouseup: MouseEvent
+Fired when the user releases the mouse button pushed on the layer.
+
+@event mouseover: MouseEvent
+Fired when the mouse enters the layer.
+
+@event mouseout: MouseEvent
+Fired when the mouse leaves the layer.
+
+@event contextmenu: MouseEvent
+Fired when the user right-clicks on the layer, prevents
+default browser context menu from showing if there are listeners on
+this event. Also fired on mobile when the user holds a single touch
+for a second (also called long press).
