Build MailQueryBuilder query

Aspose.Email Product Family

Hello,

I need a help for creating the correct MailQueryBuilder structure.
I have the following piece of code:

MessageInfoCollection col;
col = pstFolder.getContents(50, 100);

I also need to add descending order, which I’ve found to do it in this way:

MailQueryBuilder query = new MailQueryBuilder();
query.getInternalData().orderBy(false); // descending

The problem is that getContents() does not support 50, 100 and query.getQuery() arguments.
How can I do to make this query works?

Thanks

@kelberuc1,

Could you please describe more details about the issue?

Note: If you are using the trial version of Aspose.Email, only 50 emails can be extracted from the folder in a PST file. You should acquire a license for full use Aspose.Email. More details about limitations:

HI @Andrey_Potapov,

I have a valid license for Aspose.Email.Java.
I’m trying to run the following code but it’s not working for getting sorted messages:

MailQueryBuilder query = new MailQueryBuilder();
query.getInternalDate().orderBy(false); // sort the date descending 
		
List<MessageInfo> messageInfoCollection;
if (options.msgQty > 0 && options.msgStartIndex > 0)
	messageInfoCollection = pstFolder.getContents(query.getQuery()).getRange(options.msgStartIndex - 1, options.msgQty);
else
	messageInfoCollection = pstFolder.getContents(query.getQuery()); 

for (int i = 0; i < messageInfoCollection.size(); i++) 
{
	MessageInfo messageInfo = (MessageInfo) messageInfoCollection.get(i);

// do something ...
}

What can I do to make it work?

@kelberuc1,
Unfortunately, I cannot use your code example to investigate the issue because it contains unknown variable options. Could you please share a comprehensive code snippet?

@Andrey_Potapov,

Let me rewrite the code using known variables for you:

 MailQueryBuilder query = new MailQueryBuilder();
query.getInternalDate().orderBy(false); // sort the date descending 
		
List<MessageInfo> messageInfoCollection;
  messageInfoCollection = pstFolder.getContents(query.getQuery()).getRange(50, 100)

for (int i = 0; i < messageInfoCollection.size(); i++) 
{
	MessageInfo messageInfo = (MessageInfo) messageInfoCollection.get(i);

// do something ...
}

And now, is it possible to you to check?
