Examples of java.io.Reader.reset()

java.io.Reader.reset()
Reset this Readers position to the last mark() location. Invocations of read()/skip() will occur from this new location. If this Reader was not marked, the implementation of reset() is implementation specific. See the comment for the specific Reader subclass for implementation details. The default action is to throw IOException. @throws IOException If a problem occured or the receiver does not support mark()/reset().

      
      // 7. Set up a Reader over the read content
      r = getTrecDocReader(docBuf);
      // Resetting the thread's reader means it will reuse the instance
      // allocated as well as re-read from docBuf.
      r.reset();
      
      // count char length of parsed html text (larger than the plain doc body text).
      addBytes(docBuf.length()); 
    }
