遍历Lotus Domino中的每个文档(Iterating over every document in Lotus Domino)

 我想迭代（可能是大的）Lotus Domino数据库中的每个文档，并且如果处理中断（网络连接错误，应用程序重新启动等），能够从最后一个文档继续执行。 我没有对数据库的写入权限。 
 
 我正在寻找一种方法，我不必从服务器上下载那些已处理的文档。 所以，我必须将一些起始信息传递给服务器，该文档应该是（可能重新启动的）处理中的第一个。 
 
 
 
 我已经检查了AllDocuments属性和DocumentColletion.getNthDocument方法，但是这个属性是未排序的，所以我猜这个订单可以在两次调用之间改变。 
 
 
 另一个想法是使用公式查询，但似乎并没有这些查询可能的顺序。 
 
 
 第三个想法是具有相应Document.getLastModified的Database.getModifiedDocuments方法。 它看起来不错，但是在我看来，返回的集合的顺序没有记录，并且基于创建时间而不是最后修改时间。 
 以下是基于官方示例的示例代码： 
System.out.println("startDate: " + startDate);
final DocumentCollection documentCollection = 
        database.getModifiedDocuments(startDate, Database.DBMOD_DOC_DATA);

Document doc = documentCollection.getFirstDocument();
while (doc != null) {
    System.out.println("#lastmod: " + doc.getLastModified() + 
                " #created: " + doc.getCreated());
    doc = documentCollection.getNextDocument(doc);
}
 它打印以下内容： 
startDate: 2012.07.03 08:51:11 CEDT
#lastmod: 2012.07.03 08:51:11 CEDT #created: 2012.02.23 10:35:31 CET
#lastmod: 2012.08.03 12:20:33 CEDT #created: 2012.06.01 16:26:35 CEDT
#lastmod: 2012.07.03 09:20:53 CEDT #created: 2012.07.03 09:20:03 CEDT
#lastmod: 2012.07.21 23:17:35 CEDT #created: 2012.07.03 09:24:44 CEDT
#lastmod: 2012.07.03 10:10:53 CEDT #created: 2012.07.03 10:10:41 CEDT
#lastmod: 2012.07.23 16:26:22 CEDT #created: 2012.07.23 16:26:22 CEDT
 （我在这里没有使用任何AgentContext来访问数据库，数据库对象来自session.getDatabase(null, databaseName)调用。） 
 
 
 有什么方法可以用Lotus Domino Java API可靠地做到这一点？ 

I'd like iterate over every document in a (probably big) Lotus Domino database and be able to continue it from the last one if the processing breaks (network connection error, application restart etc.). I don't have write access to the database.
 
I'm looking for a way where I don't have to download those documents from the server which were already processed. So, I have to pass some starting information to the server which document should be the first in the (possibly restarted) processing.
 
 
 
I've checked the AllDocuments property and the DocumentColletion.getNthDocument method but this property is unsorted so I guess the order can change between two calls.
 
 
Another idea was using a formula query but it does not seem that ordering is possible with these queries.
 
 
The third idea was the Database.getModifiedDocuments method with a corresponding Document.getLastModified one. It seemed good but it looks to me that the ordering of the returned collection is not documented and based on creation time instead of last modification time.
 
Here is a sample code based on the official example: 
 
System.out.println("startDate: " + startDate);
final DocumentCollection documentCollection = 
        database.getModifiedDocuments(startDate, Database.DBMOD_DOC_DATA);

Document doc = documentCollection.getFirstDocument();
while (doc != null) {
    System.out.println("#lastmod: " + doc.getLastModified() + 
                " #created: " + doc.getCreated());
    doc = documentCollection.getNextDocument(doc);
}
 
It prints the following:
 
startDate: 2012.07.03 08:51:11 CEDT
#lastmod: 2012.07.03 08:51:11 CEDT #created: 2012.02.23 10:35:31 CET
#lastmod: 2012.08.03 12:20:33 CEDT #created: 2012.06.01 16:26:35 CEDT
#lastmod: 2012.07.03 09:20:53 CEDT #created: 2012.07.03 09:20:03 CEDT
#lastmod: 2012.07.21 23:17:35 CEDT #created: 2012.07.03 09:24:44 CEDT
#lastmod: 2012.07.03 10:10:53 CEDT #created: 2012.07.03 10:10:41 CEDT
#lastmod: 2012.07.23 16:26:22 CEDT #created: 2012.07.23 16:26:22 CEDT
 
(I don't use any AgentContext here to access the database. The database object comes from a session.getDatabase(null, databaseName) call.)
 
 
Is there any way to reliably do this with the Lotus Domino Java API?
