countFieldsToPrint
public int countFieldsToPrint(ReadablePeriod period, int stopAt, java.util.Locale locale)
Description copied from interface:PeriodPrinter
Returns the amount of fields from the given period that this printer will print.- Specified by:
countFieldsToPrint
in interfacePeriodPrinter
- Parameters:
period
- the period to usestopAt
- stop counting at this value, enter a number ≥ 256 to count alllocale
- the locale to use- Returns:
- amount of fields printed
-
calculatePrintedLength
public int calculatePrintedLength(ReadablePeriod period, java.util.Locale locale)
Description copied from interface:PeriodPrinter
Returns the exact number of characters produced for the given period.- Specified by:
calculatePrintedLength
in interfacePeriodPrinter
- Parameters:
period
- the period to uselocale
- the locale to use- Returns:
- the estimated length
-
printTo
public void printTo(java.lang.StringBuffer buf, ReadablePeriod period, java.util.Locale locale)
Description copied from interface:PeriodPrinter
Prints a ReadablePeriod to a StringBuffer.- Specified by:
printTo
in interfacePeriodPrinter
- Parameters:
buf
- the formatted period is appended to this bufferperiod
- the period to formatlocale
- the locale to use
-
printTo
public void printTo(java.io.Writer out, ReadablePeriod period, java.util.Locale locale) throws java.io.IOException
Description copied from interface:PeriodPrinter
Prints a ReadablePeriod to a Writer.- Specified by:
printTo
in interfacePeriodPrinter
- Parameters:
out
- the formatted period is written outperiod
- the period to formatlocale
- the locale to use- Throws:
java.io.IOException
-
parseInto
public int parseInto(ReadWritablePeriod period, java.lang.String periodStr, int position, java.util.Locale locale)
Description copied from 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.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.
- Specified by:
parseInto
in interfacePeriodParser
- Parameters:
period
- a period that will be modifiedperiodStr
- text to parseposition
- position to start parsing fromlocale
- the locale to use for parsing- Returns:
- new position, if negative, parse failed. Apply complement operator (~) to get position of failure
