Method Detail

d2j

public static final String d2j(Date d)

Marshalls a Date object to a string, such that it can be add to JSONArray or JSONObject (a.k.a., JSON-ize).

It is used with j2d(java.lang.String). d2j(java.util.Date) is used to JSON-ize a Date object, while j2d(java.lang.String) is to unmarshall it back to a Date object.

Notice it assumes TimeZones.getCurrent() (and Locale-independent). However, the result string has no time zone information. Thus, if the client is in different time zone, the date object will be different. However, since the object will be marshalled back in the same way, the value sent back from the client will be the same (regardless the time zone is different).

j2d

public static final Date j2d(String s)
                      throws ParseException

Unmarshalls a string to a date. It is used with d2j(java.util.Date). d2j(java.util.Date) is used to JSON-ize a Date object, while j2d(java.lang.String) is to unmarshall it back to a Date object.

Notice it assumes TimeZones.getCurrent() (and Locale-independent).

Throws:

ParseException
