Metadata | () | 建構函式 |
public function Metadata()| 語言版本: | ActionScript 3.0 |
| 產品版本: | OSMF 1.0 |
| 執行階段版本: | Flash Player 10, AIR 1.5 |
Constructor.
addValue | () | 方法 |
public function addValue(key:String, value:Object):void| 語言版本: | ActionScript 3.0 |
| 產品版本: | OSMF 1.0 |
| 執行階段版本: | Flash Player 10, AIR 1.5 |
Stores the specified value in this Metadata object, using the specified key. The key can subsequently be used to retrieve the value. If the key is equal to the key of another object already in the Metadata object this will overwrite the association with the new value.
參數
key:String — The key to associate the value with.
| |
value:Object — The value to add to the Metadata object.
|
擲回值
ArgumentError — If key is null or somehow invalid.
|
getValue | () | 方法 |
public function getValue(key:String):*| 語言版本: | ActionScript 3.0 |
| 產品版本: | OSMF 1.0 |
| 執行階段版本: | Flash Player 10, AIR 1.5 |
Returns the value associate with the specified key. Returns 'undefined' if the Metadata object fails to resolve the key.
參數
key:String |
* |
擲回值
ArgumentError — If key is null.
|
removeValue | () | 方法 |
public function removeValue(key:String):*| 語言版本: | ActionScript 3.0 |
| 產品版本: | OSMF 1.0 |
| 執行階段版本: | Flash Player 10, AIR 1.5 |
Removes the value associated with the specified key from this Metadata object. Returns undefined if there is no value associated with the key in this Metadata object.
參數
key:String — The key associated with the value to be removed.
|
* |
擲回值
ArgumentError — If key is null.
