 * Application users will rarely use this class directly. Instead, you
 * will use one of the factory classes to create a {@link PeriodFormatter}.

public interface PeriodParser {

     * Parses a period from the given text, at the given position, saving the
     * result into the fields of the given ReadWritablePeriod. If the parse
     * succeeds, the return value is the new text position. Note that the parse
     * may succeed without fully reading the text.
     * <p>
     * If it fails, the return value is negative, but the period may still be
     * modified. To determine the position where the parse failed, apply the
     * one's complement operator (~) on the return value.
     * @param period  a period that will be modified
     * @param periodStr  text to parse
     * @param position position to start parsing from
     * @param locale  the locale to use for parsing
     * @return new position, if negative, parse failed. Apply complement
     * operator (~) to get position of failure
     * @throws IllegalArgumentException if any field is out of range
