Re: [Classpathx-discuss] Getting only latest X messages of a newsgroup

[Cedric Hyppolite]

Hi Chris,

I see two ways:

- Get at most X latest articles: fetching the message headers using  
(last - X) or first -> last as the range in NNTPFolder.getMessages()

- Get exactly the X latest articles: fetching the message headers  
using first -> last and keeping only the latest X messages

Either way, the internal cache is used to prevent queries for  
previously downloaded messages.
Once the getMessages() returned the array of X recent messages, their  
full content can be downloaded using fetch(Message[], FetchProfile)

There would be one property (for example 'mail.nntp.limittolatest' )  
that states the number of messages to download at most or exactly.
This property should be read each time before being used so that a  
client could change the value before fetching each newsgroup.
