Method Details

getMarkedStream

public static BufferedInputStream getMarkedStream(InputStream in)

Returns a marked, rewindable stream. Calling reset() method rewinds the stream to its beginning. But reset() can fail if too long bytes were read.

isGzipped

public static boolean isGzipped(InputStream sample)
                         throws IOException

Returns wheather the stream is gzipped. This method reads a few bytes from the sample. So a caller must take care of mark() to reuse the contents. Wraping the stream by getMarkedStream() is suitable.

Throws:

IOException

getEncodingDetectors

public static List<EncodingDetector> getEncodingDetectors()

Returns the user configured ordered list of encoding detectors. This method reads property "encodingDetectors".

getDetectedEncoding

public static String getDetectedEncoding(BufferedInputStream markedStream)
                                  throws IOException

Returns an auto detected encoding from content of markedStream. This method assumes that markedStream is wrapped by getMarkedStream() method.

Throws:

IOException
