        We override default implementation to write last characters, which could be lost in buffer otherwise.
        Specified by:
        close in interface java.lang.AutoCloseable
        Specified by:
        close in interface java.io.Closeable

      • write

        public void write​(int b)
           throws java.io.IOException
        OutputStream's implementation. Our goal is to convert encoded byte stream form OutputStream to char stream, which can be written using specified writer. We perform this by collecting bytes in buffer and checking with PERIOD_SIZE interval if this buffer represents some char sequence. If so, we write to writer all chars, except last one. We don't write last char, because there still not enough bytes could be collected for it.
        Specified by:
        write in class java.io.OutputStream
        Parameters:
        b - next byte from OutputStream to write.
        Throws:
        java.io.IOException
