Constructor Detail

RMDateParser

public RMDateParser()

RMDateParser

public RMDateParser(java.util.Locale l)

RMDateParser

public RMDateParser(java.io.InputStream stream)

Constructor with InputStream.

RMDateParser

public RMDateParser(java.io.InputStream stream,
                    java.lang.String encoding)

Constructor with InputStream and supplied encoding

RMDateParser

public RMDateParser(java.io.Reader stream)

Constructor.

RMDateParser

public RMDateParser(RMDateParserTokenManager tm)

Constructor with generated Token Manager.

Method Detail

resetLocale

public void resetLocale(java.util.Locale l)

Set the locale. Currently just uses the DateFormat to figure out how to interpret "3/4/05"

setRejectsTwoDigitYears

public void setRejectsTwoDigitYears()

Y2K handling - call this to make the parser throw an error when it encounters a 2 digit year

setAcceptsTwoDigitYears

public void setAcceptsTwoDigitYears(int earliest)

Y2K handling - accept 2 digit years.

'earliest' can be anything, and is the earliest possible year that would be representable by 2 digits. setAcceptsTwoDigitYears(1920) : 00->2000, 01->2001,...,19->2019, 20->1920, 21-1921... setAcceptsTwoDigitYears(1700) : 00->1700, ... 99->1799 This is similar to DateFormatter, but they let you pick the earliest day: eg. {8/13/1920 - 8/13/2019} which seems like overkill.
