It exposes a high-level API and uses Object.observe if available, and otherwise performs dirty-checking. observe-js requires ECMAScript 5. + +### Observable + +observe-js implements a set of observers (PathObserver, ArrayObserver, ObjectObserver, CompoundObserver, ObserverTransform) which all implement the Observable interface: + +```JavaScript +{ + // Begins observation. Value changes will be reported by invoking |changeFn| with |opt_receiver| as + // the target, if provided. Returns the initial value of the observation. + open: function(changeFn, opt_receiver) {}, + + // Report any changes now (does nothing if there are no changes to report). + deliver: function() {}, + + // If there are changes to report, ignore them. Returns the current value of the observation. + discardChanges: function() {}, + + // Ends observation. Frees resources and drops references to observed objects. + close: function() {} +} +``` + +### PathObserver + +PathObserver observes a "value-at-a-path" from a given object: + +```JavaScript +var obj = { foo: { bar: 'baz' } }; +var observer = new PathObserver(obj, 'foo.bar'); +observer.open(function(newValue, oldValue) { + // respond to obj.foo.bar having changed value. +}); +``` + +PathObserver will report a change whenever the value obtained by the corresponding path expression (e.g. `obj.foo.bar`) would return a different value. + +PathObserver also exposes a `setValue` method which attempts to update the underlying value. Setting the value does not affect notification state (in other words, a caller sets the value but does not `discardChanges`, the `changeFn` will be notified of the change). + +```JavaScript +observer.setValue('boo'); +assert(obj.foo.bar == 'boo'); +``` + +Notes: + * If the path is ever unreachable, the value is considered to be `undefined`. + * If the path is empty (e.g. `''`), it is said to be the empty path and its value is its root object. + * PathObservation respects values on the prototype chain + +### ArrayObserver + +ArrayObserver observes the index-positions of an Array and reports changes as the minimal set of "splices" which would have had the same effect. + +```JavaScript +var arr = [0, 1, 2, 4]; +var observer = new ArrayObserver(arr); +observer.open(function(splices) { + // respond to changes to the elements of arr. + splices.forEach(function(splice) { + splice.index; // index position that the change occurred. + splice.removed; // an array of values representing the sequence of elements which were removed + splice.addedCount; // the number of elements which were inserted. + }); +}); +``` + +ArrayObserver also exposes a utility function: `applySplices`. The purpose of `applySplices` is to transform a copy of an old state of an array into a copy of its current state, given the current state and the splices reported from the ArrayObserver. + +```JavaScript +AraryObserver.applySplices = function(previous, current, splices) { } +``` + +### ObjectObserver + +ObjectObserver observes the set of own-properties of an object and their values. + +```JavaScript +var myObj = { id: 1, foo: 'bar' }; +var observer = new ObjectObserver(myObj); +observer.open(function(added, removed, changed, getOldValueFn) { + // respond to changes to the obj. + Object.keys(added).forEach(function(property) { + property; // a property which has been been added to obj + added[property]; // its value + }); + Object.keys(removed).forEach(function(property) { + property; // a property which has been been removed from obj + getOldValueFn(property); // its old value + }); + Object.keys(changed).forEach(function(property) { + property; // a property on obj which has changed value. + changed[property]; // its value + getOldValueFn(property); // its old value + }); +}); +``` + +### CompoundObserver + +CompoundObserver allows simultaneous observation of multiple paths and/or Observables. It reports any and all changes in to the provided `changeFn` callback. + +```JavaScript +var obj = { + a: 1, + b: 2, +}; + +var otherObj = { c: 3 }; + +var observer = new CompoundObserver(); +observer.addPath(obj, 'a'); +observer.addObserver(new PathObserver(obj, 'b')); +observer.addPath(otherObj, 'c'); +observer.open(function(newValues, oldValues) { + // Use for-in to iterte which values have changed. + for (var i in oldValues) { + console.log('The ' + i + 'th value changed from: ' + newValues[i] + ' to: ' + oldValues[i]); + } +}); +``` + + +### ObserverTransform + +ObserverTransform is used to dynamically transform observed value(s). + +```JavaScript +var obj = { value: 10 }; +var observer = new PathObserver(obj, 'value'); +function getValue(value) { return value * 2 }; +function setValue(value) { return value / 2 }; + +var transform = new ObserverTransform(observer, getValue, setValue); + +// returns 20. +transform.open(function(newValue, oldValue) { + console.log('new: ' + newValue + ', old: ' + oldValue); +}); + +obj.value = 20; +transform.deliver(); // 'new: 40, old: 20' +transform.setValue(4); // obj.value === 2; +``` + +ObserverTransform can also be used to reduce a set of observed values to a single value: + +```JavaScript +var obj = { a: 1, b: 2, c: 3 }; +var observer = new CompoundObserver(); +observer.addPath(obj, 'a'); +observer.addPath(obj, 'b'); +observer.addPath(obj, 'c'); +var transform = new ObserverTransform(observer, fuction(values) { + var value = 0; + for (var i = 0; i < values.length; i++) + value += values[i] + return value; +}); + +// returns 6. +transform.open(function(newValue, oldValue) { + console.log('new: ' + newValue + ', old: ' + oldValue); +}); + +obj.a = 2; +obj.c = 10; +transform.deliver(); // 'new: 14, old: 6' +``` + +### Path objects + +A path is an ECMAScript expression consisting only of identifiers (`myVal`), member accesses (`foo.bar`) and key lookup with literal values (`arr[0]` `obj['str-value'].bar.baz`). + +`Path.get('foo.bar.baz')` returns a Path object which represents the path. Path objects have the following API: + +```JavaScript +{ + // Returns the current of the path from the provided object. If eval() is available, a compiled getter will be + // used for better performance. + getValueFrom: function(obj) { } + + + // Attempts to set the value of the path from the provided object. Returns true IFF the path was reachable and + // set. + setValueFrom: function(obj, newValue) { } +} +``` + +Path objects are interned (e.g. `assert(Path.get('foo.bar.baz') === Path.get('foo.bar.baz'));`) and are used internally to avoid excessive parsing of path strings. Observers which take path strings as arguments will also accept Path objects. + +## About delivery of changes + +observe-js is intended for use in environments which implement Object.observe, but it supports use in environments which do not. + +If `Object.observe` is present, and observers have changes to report, their callbacks will be invoked at the end of the current turn (microtask). In a browser environment, this is generally at the end of an event. + +If `Object.observe` is absent, `Platform.performMicrotaskCheckpoint()` must be called to trigger delivery of changes. If `Object.observe` is implemented, `Platform.performMicrotaskCheckpoint()` has no effect. diff --git a/bower_components/observe-js/benchmark/benchmark.js b/bower_components/observe-js/benchmark/benchmark.js new file mode 100644 index 00000000..109cd16e --- /dev/null +++ b/bower_components/observe-js/benchmark/benchmark.js @@ -0,0 +1,183 @@ +/* + * Copyright (c) 2014 The Polymer Project Authors.
