Method Details

countFieldsToPrint

public int countFieldsToPrint(ReadablePeriod period,
 int stopAt,
 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 interface PeriodPrinter

Parameters:

period - the period to use

stopAt - stop counting at this value, enter a number ≥ 256 to count all

locale - the locale to use

Returns:

amount of fields printed

calculatePrintedLength

public int calculatePrintedLength(ReadablePeriod period,
 Locale locale)

Description copied from interface: PeriodPrinter

Returns the exact number of characters produced for the given period.

Specified by:

calculatePrintedLength in interface PeriodPrinter

Parameters:

period - the period to use

locale - the locale to use

Returns:

the estimated length

printTo

public void printTo(StringBuffer buf,
 ReadablePeriod period,
 Locale locale)

Description copied from interface: PeriodPrinter

Prints a ReadablePeriod to a StringBuffer.

Specified by:

printTo in interface PeriodPrinter

Parameters:

buf - the formatted period is appended to this buffer

period - the period to format

locale - the locale to use

printTo

public void printTo(Writer out,
 ReadablePeriod period,
 Locale locale)
             throws IOException

Description copied from interface: PeriodPrinter

Prints a ReadablePeriod to a Writer.

Specified by:

printTo in interface PeriodPrinter

Parameters:

out - the formatted period is written out

period - the period to format

locale - the locale to use

Throws:

IOException - if an IO error occurs

parseInto

public int parseInto(ReadWritablePeriod period,
 String periodStr,
 int position,
 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 interface PeriodParser

Parameters:

period - a period that will be modified

periodStr - text to parse

position - position to start parsing from

locale - the locale to use for parsing

Returns:

new position, if negative, parse failed. Apply complement operator (~) to get position of failure

decompose

private void decompose(List<Object> elementPairs,
 List<Object> printerList,
 List<Object> parserList)

addArrayToList

private void addArrayToList(List<Object> list,
 Object[] array)
