Are you using something other than GAE? Why do you want to persist the
object with php?
Here is an example using JDO's.
@PersistenceCapable
public class Pair implements IsSerializable {
@PrimaryKey
public long encodedKey;
@Persistent
public String mName;
@Persistent
public String mValue;
}
You can persist page one by doing the following.
JDOHelper.getPersistenceManagerFactory("transactions-
optional").getPersistenceManager().makePersistent(page1);
You can retrieve all page objects by doing the following. If you want
one specific page, then add filters to the query.
JDOHelper.getPersistenceManagerFactory("transactions-
optional").getPersistenceManager().newQuery(Pages.class).execute();
When you pass the object from the server to the client, it will
automatically be serialized and deserialized.
Hope that helps,
Tom
