+ * An interface for a view contact.
+ *
+ * As the name already says the view contact is a contact in a view.
+ * It contains the fields that were defined in the sort order of the view.
+ * However, a store implementation possibly have limitations of field types
+ * that can be used in the sort order. If the store doesn't support the given
+ * field type in a view contact it sets the data of those fields to zero length.
+ * The order of the fields are same as in a sort order.
