[OpenLayers-Users] Augmenting a method?

[Jeff Dege]

In a derived class, how do I override a method, and then call the
parent's implementation of that method?

In C++:

   class Foo()
   {
      virtual void snaffle() { cout << "Snaffle!" << endl; }
   }

   class Bar: public Foo
   {
      virtual void snaffle() { Foo::snaffle(); Foo::snaffle(); }
   }

In OpenLayers Javascript?


OpenLayers.Layer.MyGML = OpenLayers.Class.create();
OpenLayers.Layer.MyGML.prototype = 
  OpenLayers.Class.inherit( OpenLayers.Layer.GML, {
     initialize: function(name, url, options) {
        var newArguments = new Array()
        newArguments.push(name, options);
        OpenLayers.Layer.GML.prototype.initialize.apply(this,
newArguments);
        this.url = url;
    },
    addFeatures: function(features) {
		How???
	},
    /** @final @type String */
    CLASS_NAME: "OpenLayers.Layer.MyGML"
    });
