How can I find out if a string is parseable with jodatimes DateTime constructor?

Question

I need to determine if an input string input can be parsed by jodatimes DateTime constructor Datetime(Object instant) but I'm not interested in creating the DateTime object at this time.

Is there any way to check if the string is parseable beside calling the constructor and catch the possible exception?

Answer 1

ConvertManager.getInstance().getInstantConverter() is what the constructor uses to see if there is a matching converted. However, it also thrown an exception.

But I that constructor would only consult the ISODateTimeFormat. If you want to specify a custom format:

DateTimeFormatter dtf = DateTimeFormat.forPattern(format);
dtf.parseDateTime(dateTimeString);

Alas, again you'd have to catch an IllegalArgumentException
