Not readily. Charles leaves that to the user. There is a persistent extension to the BC by Adams (?), cf. the web site. If all goes well, Ada2005 will feature persistent containers, cf. AI-302. I don't know of any other persistent container library. I'm working on it though...

I think that persistence should be an absolute requirement for any 
container library. I've implemented my own with the ability to write to 
a stream file. It works nicely for things that don't need a really 
sophisticated database.

"Charles... BC+... I don't know of any other persistent container library." (myself)
 
Maybe one more: in the AI-302/2 discussion I mentioned Martin Kirshik's AdaCL has being either of indefinite elements or persistent. I cannot remember which feature now. Maybe both. Martin?
