You can set up "private" items (context variables available to some public interface) in the construct's init() method.
- > can.Construct.extend("Bar", { init : function() { var b = 0; this.binc = function(){ return ++b; }; } });function Constructor() { // All construction is actually done in the init method. if (!initializing) { return this.constructor !== Constructor && // We are being called without `new` or we are extending. arguments.length && Constructor.constructorExtends ? Constructor.extend.apply(Constructor, arguments) : // We are being called with `new`. Constructor.newInstance.apply(Constructor, arguments); } } dashboard.js:13297> b = new Bar();Constructor {binc: function, init: function, constructor: function, setup: function, proxy: function}> b.binc()1> b.binc()2> b.binc()3> c = new Bar()Constructor {binc: function, init: function, constructor: function, setup: function, proxy: function}> c.binc()1> c.binc()2> b.binc()4
