| * Marker interface for an object that GemFire creates and returns from |
| * {@link PdxReader#readUnreadFields() readUnreadFields}. If you call readUnreadFields then you must |
| * also call {@link PdxWriter#writeUnreadFields(PdxUnreadFields) writeUnreadFields} when that object |
| * is reserialized. If you do not call {@link PdxWriter#writeUnreadFields(PdxUnreadFields) |
| * writeUnreadFields} but you did call {@link PdxReader#readUnreadFields() readUnreadFields} the |
| * unread fields will not be written. |
| * <p> |
| * Unread fields are those that are not explicitly read with a {@link PdxReader} readXXX method. |
| * This should only happen when a domain class has changed by adding or removing one or more fields. |
| * Unread fields will be preserved automatically (unless you turn this feature off using |
| * {@link org.apache.geode.cache.CacheFactory#setPdxIgnoreUnreadFields(boolean) |
| * setPdxIgnoreUnreadFields} or |
| * {@link org.apache.geode.cache.client.ClientCacheFactory#setPdxIgnoreUnreadFields(boolean) client |
| * setPdxIgnoreUnreadFields}) but to reduce the performance and memory overhead of automatic |
| * preservation it is recommended that use {@link PdxReader#readUnreadFields() readUnreadFields} if |
| * possible. |
