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. 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.
