      public boolean isDone()

    • getDetectedCharset

      public DetectedCharset getDetectedCharset()
      返回:
      The detected encoding is returned. If the detector couldn't determine what encoding was used, null is returned.

    • getListener

      public CharsetListener getListener()

    • handleData

      public void handleData(byte[] buf)
      Feed the detector with more data.
      参数:
      buf - Buffer with the data

    • handleData

      public void handleData(byte[] buf, int offset, int length)
      Feed the detector with more data.
      参数:
      buf - Buffer with the data

      buf - Buffer with the data
      offset - initial position of data in buf
      length - length of data

    • detectCharsetFromBOM

      public static DetectedCharset detectCharsetFromBOM(byte[] buf)

    • dataEnd

      public void dataEnd()
      Marks end of data reading. Finish calculations.

    • reset

      public void reset()
      Resets detector to be used again.
