Examples of java.io.StringReader.reset()

java.io.StringReader.reset()
Resets the stream to the most recent mark, or to the beginning of the string if it has never been marked. @exception IOException If an I/O error occurs

                reader = new StringReader(headerValue);
                // get the first character to decide - expect '(' or '<'
                try {
                    reader.mark(1);
                    firstChar = readWhiteSpace(reader);
                    reader.reset();
                } catch (IOException ignore) {
                    // may be thrown according to API but is only thrown by the
                    // StringReader class if the reader is already closed.
                }
