      public Charset detect(InputStream input, Metadata metadata) throws IOException
      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.

      Specified by:
      detect in interface EncodingDetector
      input - text document input stream, or null
      metadata - input metadata for the document
      detected character encoding, or null
      IOException - if the document input stream could not be read
    • isStripMarkup

      public boolean isStripMarkup()
    • setStripMarkup

      @Field public void setStripMarkup(boolean stripMarkup)
      Whether or not to attempt to strip html-ish markup from the stream before sending it to the underlying detector.

      The underlying detector may still apply its own stripping if this is set to false.

      stripMarkup - whether or not to attempt to strip markup before sending the stream to the underlying detector

      @Field public void setMarkLimit(int markLimit)
      How far into the stream to read for charset detection. Default is 12000.
