Functions
-
all(List array, Function test)
→ bool
-
Checks whether all elements of the array pass the test.
Function test gets 3 arguments passed:
-
any(List array, Function test)
→ bool
-
Checks whether any element of the array passes the test.
Function test gets 3 arguments passed:
-
apply(List array, Function f, [dynamic context])
→ dynamic
-
Applies a function f to all elements of an array.
Function f gets 3 arguments passed:
-
arrayIndexOf(List array, dynamic item)
→ num
-
-
buildQueryString(dynamic data)
→ String
-
-
decycleObject(dynamic object)
→ dynamic
-
See https://github.com/douglascrockford/JSON-js/blob/master/cycle.js
Remove circular references from an object. Required for JSON.stringify in
React Native, which tends to blow up a lot.
-
encodeParamsObject(dynamic data)
→ String
-
-
extend(dynamic target, [dynamic sources1, dynamic sources2, dynamic sources3, dynamic sources4, dynamic sources5])
→ dynamic
-
Merges multiple objects into the target argument.
For properties that are plain Objects, performs a deep-merge. For the
rest it just copies the value of the property.
To extend prototypes use it as following:
Pusher.Util.extend(Target.prototype, Base.prototype)
You can also use it to merge objects without altering them:
Pusher.Util.extend({}, object1, object2)
-
filter(List array, Function test)
→ List
-
Filters elements of the array using a test function.
Function test gets 4 arguments passed:
-
filterObject(Object object, Function test)
→ dynamic
-
Filters properties of the object using a test function.
Function test gets 4 arguments passed:
-
flatten(Object object)
→ List
-
Flattens an object into a two-dimensional array.
-
keys(dynamic object)
→ List<String>
-
Return a list of objects own proerty keys
-
map(List array, Function f)
→ List
-
Maps all elements of the array and returns the result.
Function f gets 4 arguments passed:
-
mapObject(dynamic object, Function f)
→ dynamic
-
Maps all elements of the object and returns the result.
Function f gets 4 arguments passed:
-
objectApply(dynamic object, Function f)
→ dynamic
-
Applies a function f to all properties of an object.
Function f gets 3 arguments passed:
-
safeJSONStringify(dynamic source)
→ String
-
Provides a cross-browser and cross-platform way to safely stringify objects
into JSON. This is particularly necessary for ReactNative, where circular JSON
structures throw an exception.
-
stringify()
→ String
-
-
values(dynamic object)
→ List
-
Return a list of object's own property values
