decodeToByteArray(base64String:String):ByteArray [static]
Decodes a Base64-encoded string and returns the result. | Base64 | ||
decodeToString(base64String:String, decodeAsUTF:Boolean = true):String [static]
Decodes a Base64-encoded string and returns the string result. | Base64 | ||

Returns a Base64-encoded string. | Base64 | ||
| codePage | property |
codePage:StringIdentifies the code page to use when decoding non-UTF8 strings containing "high ascii" characters. The empty string ("") specifies the default code page for the system.
The default value is "".
public static function get codePage():String public static function set codePage(value:String):void| decodeToByteArray | () | method |
public static function decodeToByteArray(base64String:String):ByteArrayDecodes a Base64-encoded string and returns the result.
Parameters
base64String:String — The string to decode.
|
ByteArray — A ByteArray containing the decoded data from base64String.
|
| decodeToString | () | method |
public static function decodeToString(base64String:String, decodeAsUTF:Boolean = true):StringDecodes a Base64-encoded string and returns the string result.
This method invokes the decodeToByteArray method
and then returns the result of calling a string conversion
method on the resulting ByteArray.
Parameters
base64String:String — The string to decode.
| |
decodeAsUTF:Boolean (default = true)true (the default), the
readUTFBytes method will be used to convert the ByteArray to a String. If
this value is false, the readMultiByte method will be used for
conversion. Note that in the second case, the value of the codePage property
is used to determine how to process "high ascii" characters.
|
String — A string containing the decoded data from base64String.
