Base64Decoder

()Constructor
public function Base64Decoder()

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Constructor.

Method Detail

decode

()method
public function decode(encoded:String):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Decodes a Base64 encoded String and adds the result to an internal buffer. Strings must be in ASCII format.

Subsequent calls to this method add on to the internal buffer. After all data have been encoded, call toByteArray() to obtain a decoded flash.utils.ByteArray.

Parameters

encoded:String — The Base64 encoded String to decode.

reset

()method 
public function reset():void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Clears all buffers and resets the decoder to its initial state.

toByteArray

()method 
public function toByteArray():ByteArray

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Returns the current buffer as a decoded flash.utils.ByteArray. Note that calling this method also clears the buffer and resets the decoder to its initial state.

Returns
ByteArray — The decoded flash.utils.ByteArray.
