/** * Finds the index in the given buffer of a newline character, either the first or the last (based on the parameters). * If a combined newline (\r\n), the index returned is that of the last character in the sequence. * * @param buffer The buffer to search in. * @param startOffset The index of the first byte to start searching at. * @param length The number of bytes to search, starting from the given startOffset. * @param reverse If true, searches from the startOffset down to the beginning of the buffer. If false, searches upwards. * @param encoding Indicates the type of encoding to use for the buffered bytes. * @param delimiter Optionally indicates the delimiter to consider as the "new line", which MUST BE a single character. If null, the default is '\\r', '\\n' and '\\r\\n'. * @return The index of the closest newline character in the sequence (based on direction) that was found.
