clone | () | yöntem |
public static function clone(value:Object):Object
Dil Sürümü: | ActionScript 3.0 |
Ürün Sürümü: | Flex 4 |
Çalışma Zamanı Sürümleri: | Flash Player 9, AIR 1.1 |
Clones the specified Object and returns a reference to the clone. The clone is made using a native serialization technique. This means that custom serialization will be respected during the cloning. clone() differs from copy() in that the uid property of each object instance is retained.
This method is designed for cloning data objects,
such as elements of a collection. It is not intended for cloning
a UIComponent object, such as a TextInput control. If you want to clone
specific UIComponent objects, you can create a subclass of the component
and implement a clone()
method.
Parametreler
value:Object — Object that should be cloned.
|
Object — Clone of the specified Object.
|
compare | () | yöntem |
public static function compare(a:Object, b:Object, depth:int = -1):int
Dil Sürümü: | ActionScript 3.0 |
Ürün Sürümü: | Flex 3 |
Çalışma Zamanı Sürümleri: | Flash Player 9, AIR 1.1 |
Compares the Objects and returns an integer value
indicating if the first item is less than greater than or equal to
the second item.
This method will recursively compare properties on nested objects and
will return as soon as a non-zero result is found.
By default this method will recurse to the deepest level of any property.
To change the depth for comparison specify a non-negative value for
the depth
parameter.
Parametreler
a:Object — Object.
| |
b:Object — Object.
| |
depth:int (default = -1 ) — Indicates how many levels should be
recursed when performing the comparison.
Set this value to 0 for a shallow comparison of only the primitive
representation of each property.
For example:var a:Object = {name:"Bob", info:[1,2,3]}; var b:Object = {name:"Alice", info:[5,6,7]}; var c:int = ObjectUtil.compare(a, b, 0); In the above example the complex properties of |
int — Return 0 if a and b are null, NaN, or equal.
Return 1 if a is null or greater than b.
Return -1 if b is null or greater than a.

Copies the specified Object and returns a reference to the copy. The copy is made using a native serialization technique. This means that custom serialization will be respected during the copy.
This method is designed for copying data objects,
such as elements of a collection. It is not intended for copying
a UIComponent object, such as a TextInput control. If you want to create copies
of specific UIComponent objects, you can create a subclass of the component and implement
a clone()
method, or other method to perform the copy.
Parametreler
value:Object — Object that should be copied.

Pretty-prints the specified Object into a String. All properties will be in alpha ordering. Each object will be assigned an id during printing; this value will be displayed next to the object type token preceded by a '#', for example:
(mx.messaging.messages::AsyncMessage)#2.
This id is used to indicate when a circular reference occurs.
Properties of an object that are of the Class
type will
appear only as the assigned type.
For example a custom definition like the following:
public class MyCustomClass { public var clazz:Class; }
With the clazz
property assigned to Date
will display as shown below:
(somepackage::MyCustomClass)#0 clazz = (Date)
Parametreler
value:Object — Object to be pretty printed.
| |
namespaceURIs:Array (default = null ) — Array of namespace URIs for properties
that should be included in the output.
By default only properties in the public namespace will be included in
the output.
To get all properties regardless of namespace pass an array with a
single element of ".
| |
exclude:Array (default = null ) — Array of the property names that should be
excluded from the output.
Use this to remove data from the formatted string.
|
String — String containing the formatted version
of the specified object.
