// Model tracking
// --------------
//
// This is the central feature of Knockout-ES5. We augment model objects by converting properties
// into ES5 getter/setter pairs that read/write an underlying Knockout observable. This means you can
// use plain JavaScript syntax to read/write the property while still getting the full benefits of
// Knockout's automatic dependency detection and notification triggering.
//
// For comparison, here's Knockout ES3-compatible syntax:
//
//     var firstNameLength = myModel.user().firstName().length; // Read
//     myModel.user().firstName('Bert'); // Write
//
// ... versus Knockout-ES5 syntax:
//
//     var firstNameLength = myModel.user.firstName.length; // Read
//     myModel.user.firstName = 'Bert'; // Write
// `ko.track(model)` converts each property on the given model object into a getter/setter pair that
// wraps a Knockout observable. Optionally specify an array of property names to wrap; otherwise we
// wrap all properties. If any of the properties are already observables, we replace them with
// ES5 getter/setter pairs that wrap your original observable instances. In the case of readonly
// ko.computed properties, we simply do not define a setter (so attempted writes will be ignored,
// which is how ES5 readonly properties normally behave).
//
// By design, this does *not* recursively walk child object properties, because making literally
// everything everywhere independently observable is usually unhelpful. When you do want to track
// child object properties independently, define your own class for those child objects and put
// a separate ko.track call into its constructor --- this gives you far more control.

// Array handling
// --------------
//
// Arrays are special, because unlike other property types, they have standard mutator functions
// (`push`/`pop`/`splice`/etc.) and it's desirable to trigger a change notification whenever one of
// those mutator functions is invoked.
//
// Traditionally, Knockout handles this by putting special versions of `push`/`pop`/etc. on observable
// arrays that mutate the underlying array and then trigger a notification. That approach doesn't
// work for Knockout-ES5 because properties now return the underlying arrays, so the mutator runs
// in the context of the underlying array, not any particular observable:
//
//     // Operates on the underlying array value
//     myModel.someCollection.push('New value');
//
// To solve this, Knockout-ES5 detects array values, and modifies them as follows:
//  1. Associates a hidden subscribable with each array instance that it encounters
//  2. Intercepts standard mutators (`push`/`pop`/etc.) and makes them trigger the subscribable
// Then, for model properties whose values are arrays, the property's underlying observable
// subscribes to the array subscribable, so it can trigger a change notification after mutation.
// Given an observable that underlies a model property, watch for any array value that might
// be assigned as the property value, and hook into its change events
function m(a,b){var c=null;a.computed(function(){
// Unsubscribe to any earlier array instance
c&&(c.dispose(),c=null);
// Subscribe to the new array instance
var d=b();d instanceof Array&&(c=n(a,b,d))})}
// Listens for array mutations, and when they happen, cause the observable to fire notifications.
// This is used to make model properties of type array fire notifications when the array changes.
// Returns a subscribable that can later be disposed.
function n(a,b,c){var d=o(a,c);return d.subscribe(b)}
// Gets or creates a subscribable that fires after each array mutation
function o(a,b){z||(z=x());var c=z.get(b);if(!c){c=new a.subscribable,z.set(b,c);var d={};p(b,c,d),q(a,b,c,d)}return c}
// After each array mutation, fires a notification on the given subscribable
function p(a,b,c){["pop","push","reverse","shift","sort","splice","unshift"].forEach(function(d){var e=a[d];a[d]=function(){var a=e.apply(this,arguments);return c.pause!==!0&&b.notifySubscribers(this),a}})}
// Adds Knockout's additional array mutation functions to the array
function q(a,b,c,d){["remove","removeAll","destroy","destroyAll","replace"].forEach(function(e){
// Make it a non-enumerable property for consistency with standard Array functions
Object.defineProperty(b,e,{enumerable:!1,value:function(){var f;
// These additional array mutators are built using the underlying push/pop/etc.
// mutators, which are wrapped to trigger notifications. But we don't want to
// trigger multiple notifications, so pause the push/pop/etc. wrappers and
// delivery only one notification at the end of the process.

// Creates a temporary observableArray that can perform the operation.
f=a.observableArray.fn[e].apply(a.observableArray(b),arguments)}finally{d.pause=!1}return c.notifySubscribers(b),f}})})}
// Static utility functions
// ------------------------
//
// Since Knockout-ES5 sets up properties that return values, not observables, you can't
// trivially subscribe to the underlying observables (e.g., `someProperty.subscribe(...)`),
// or tell them that object values have mutated, etc. To handle this, we set up some
// extra utility functions that can return or work with the underlying observables.
// Returns the underlying observable associated with a model property (or `null` if the
// model or property doesn't exist, or isn't associated with an observable). This means
// you can subscribe to the property, e.g.:
//
//     ko.getObservable(model, 'propertyName')
//       .subscribe(function(newValue) { ... });
