Class JsonDateDeserializer

java.lang.Object

com.fasterxml.jackson.databind.JsonDeserializer<java.util.Date>

org.jasig.portlet.notice.JsonDateDeserializer

All Implemented Interfaces:

com.fasterxml.jackson.databind.deser.NullValueProvider

public class JsonDateDeserializer
extends com.fasterxml.jackson.databind.JsonDeserializer<java.util.Date>

Apparently there is no standard format for dates in JSON. JsonLib (which this portlet previously used) essentially serialized an instance of java.util.Date like any other object. Jackson, however, (the current method) converts the date to "epoch time" (a long representing milliseconds since January 1, 1970, 00:00:00 GMT). The Jackson approach isn't that useful, since it becomes hard to detect what is a date. This class is responsible for telling Jackson to use the former method.
