| org.joda.time.format.PeriodParser | 
Internal interface for parsing textual representations of time periods.
 Application users will rarely use this class directly. Instead, you
 will use one of the factory classes to create a PeriodFormatter.
 
 The factory classes are:
 - PeriodFormatterBuilder
 - PeriodFormat
 - ISOPeriodFormat

   | |||||||||||
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.
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.
| period | a period that will be modified | 
|---|---|
| periodStr | text to parse | 
| position | position to start parsing from | 
| locale | the locale to use for parsing | 
| IllegalArgumentException | if any field is out of range |
