LZMA AS FLASH 压缩算法

as3 实现的lzma解码, 从官方的java代码移植过来的。 使用例子 public static function decode(src:ByteArray) : ByteArray { if (src == null || src.length < 16) { return null; } var inStream:InputStream = new InputStream(src); var propertiesSize:int = 5; var properties:Vector. = new Vector.(propertiesSize); if (inStream.readVOL(properties, 0, propertiesSize) != propertiesSize) return null; var decoder:Decoder = new Decoder(); if (!decoder.SetDecoderProperties(properties)) return null; var outSize:uint = 0; for (var i:int = 0; i < 8; i++) { var v:int = inStream.read(); if (v < 0) return null; outSize |= (v << (8 * i)); } var ret:ByteArray = new ByteArray(); ret.length = outSize; var outStream:OutputStream = new OutputStream(ret); if (!decoder.Code(inStream, outStream, outSize)) return null; inStream.close(); outStream.close(); ret.position =0; return ret; }
