    Description copied from interface: EncodingDetector
    
    Detects the character encoding of the given text document, or null if the encoding of the document can not be detected.
    If the document input stream is not available, then the first argument may be null. Otherwise the detector may read bytes from the start of the stream to help in encoding detection. The given stream is guaranteed to support the mark feature and the detector is expected to mark the stream before reading any bytes from it, and to reset the stream before returning. The stream must not be closed by the detector.
    The given input metadata is only read, not modified, by the detector.

    Throws:
    
    IOException - if the document input stream could not be read
