Methods

static defineLazyProperty(obj, key, getValue, setter)

utils/obj.js, line 160

Object.defineProperty but "lazy", which means that the value is only set after it is retrieved the first time, rather than being set right away.

Parameters:

Name	Type	Description
obj	Object	the object to set the property on
key	string	the key for the property to set
getValue	function	the function used to get the value when it is needed.
setter	boolean	whether a setter should be allowed or not

static each(object, fn)

utils/obj.js, line 58

Array-like iteration for objects.

Parameters:

Name	Type	Description
object	Object	The object to iterate over
fn	obj:EachCallback	The callback function which is called for each key in the object.

static isObject(value) → {boolean}

utils/obj.js, line 93

Returns whether a value is an object of any kind - including DOM nodes, arrays, regular expressions, etc. Not functions, though.

This avoids the gotcha where using typeof on a null value results in 'object'.

Parameters:

Name	Type	Description
value	Object

Returns:

boolean

static isPlain(value) → {boolean}

utils/obj.js, line 104

Returns whether an object appears to be a "plain" object - that is, a direct instance of Object.

Parameters:

Name	Type	Description
value	Object

Returns:

boolean

static merge(sources) → {Object}

utils/obj.js, line 126

Merge two objects recursively.

Performs a deep merge like lodash.merge, but only merges plain objects (not arrays, elements, or anything else).

Non-plain object values will be copied directly from the right-most argument.

Parameters:

Name	Type	Description
sources	Array.<Object>	One or more objects to merge into a new object.

Returns:

Object -

A new object that is the merged result of all sources.

static reduce(object, fn, initialopt) → {*}

utils/obj.js, line 79

Array-like reduce for objects.

Parameters:

Name	Type	Attributes	Default	Description
object	Object			The Object that you want to reduce.
fn	function			A callback function which is called for each key in the object. It receives the accumulated value and the per-iteration value and key as arguments.
initial	*	<optional>	0	Starting value

Returns:

* -

The final accumulated value.

Type Definitions

obj:EachCallback(value, key)

utils/obj.js, line 6

Parameters:

Name	Type	Description
value	*	The current key for the object that is being iterated over.
key	string	The current key-value for object that is being iterated over

obj:ReduceCallback(accum, value, key) → {*}

utils/obj.js, line 16

Parameters:

Name	Type	Description
accum	*	The value that is accumulating over the reduce loop.
value	*	The current key for the object that is being iterated over.
key	string	The current key-value for object that is being iterated over

Returns:

* -

The new accumulated value.
