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

java.nio.charset.CharsetEncoder.canEncode()
Check if given character can be encoded by this encoder. Note that this method can change the internal status of this encoder, so it should not be called when another encode process is ongoing, otherwise it will throw IllegalStateException. This method can be overriden for performance improvement. @param c the given encoder @return true if given character can be encoded by this encoder @throws IllegalStateException if another encode process is ongoing so that current internal status is neigher RESET or FLUSH
