Examples of java.nio.charset.CharsetEncoder.reset()

java.nio.charset.CharsetEncoder.reset()
Reset this encoder. This method will reset internal status, and then call implReset() to reset any status related to specific charset. @return this encoder

        Map<Charset, CharsetEncoder> map = encoders.get();
        CharsetEncoder e = map.get(charset);
