[NET] FTP client object lifespan
OK. This is probably a dumb question but I'll ask anyway.
What is the lifespan of an FTPClient object?
OR.... Do I need to recreate the configuration information each time I
connect and disconnect?
What I plan on doing is making an application that periodically monitors
for any file changes on an ftp server. (VFS is supposed to do this but
currently doesn't. I've had a bug logged for a while now but I got tired
of waiting)
What I want to do is set up the configuration information (system type,
IP address / Host name, user ID, password, etc) for the FTPClient and
use this with my monitor, connecting, checking the file for lastModified
time and then disconnecting. This will be done every few hours or so.
I don't particularly want to have to set up the config information each
time as I'm trying to make the monitor as generic as possible to monitor
multiple ftp locations, with differing configurations. (Basically I want
to call the monitor with an FTPClient objects and it will monitor a file
specified for each object)
I know that the disconnect resets the configuration to default but I'm
wondering if there's any way to have an FTPClient object that retains it
all so I just need to connect, check the files and disconnect.
Thanks in advance for any help.
All the best,
Tony

Hi again Rory.
Yes, I could, and probably will.
I was just hoping that there was an easy way (read: built in) to keep
state of the FTPClient connection so that an automated process wouldn't
need to have that information re-entered.
I was just being lazy.
Thanks for your help Rory. It is greatly appreciated.
All the best,
Tony

It wouldnt be too difficult to subclass or wrap FTPClient and keep
whatever state you need in the wrapper or subclass object. This could be
an easy way to do what you need to do.

You'll need to provide this info on reconnect.
Thanks

RE: [NET] FTP client object lifespan

Hi Rory.
Basically I'm talking about everything needed to connect to a server.
- login/password information
- host / IP address of server
- passive / active connection information
- system type
- timezone, etc
- basically everything to do with setting up a connection to a server
That way you can connect and disconnect from the server just by calling
connect() or disconnect() without having to set up the FTPClient every
time.
The file monitor program I'm writing (with regards to FTP) requires that
I pass through an object and the filename to monitor, but this could be
multiple FTP locations with files for each location.
With the FTPClient as it stands I would need to set up the connection
each time I connected because the disconnect would reset everything back
to defaults.
I hope that explains it better.
All the best,
Tony

Not really sure I understand the question - what configuration
