  org.eclipse.smila.datamodel.util.AnyUtil

public final class AnyUtil
extends java.lang.Object

utility class for handling / conversion of Any objects. Hint: The Any-to-JSON conversion for Date(Time)s is not symmetric. If the Any object contains Date(Time) values, they will be serialized to String values in simple timestamp format. But when parsing JSON to an Any object, Date(Time) strings will not be recognized anymore, but just read as String values.
