I have a FTP client which has multiple servers configured by the user at
runtime:
class FTPConnection
{
FTPConnection(ServerInfo server, UserInfo user)...
}
I also have a client class which does something with the connection:
class DoSomethingWithFTP
{
DoSomethingWithFTP(FTPConnection conn)...
}
For example, one type of DoSomethingWithFTP might be a DownloadAllTheThings
process.
What I'd like to do is have a notion of a "current connection" which
is analogous to the "current user". Nevermind that I probably wouldn't
write code like this, all I want to do is figure out how I would inject the
"current" FTP connection!
So as you can see, a FTP connection requires some server info and user
info. This is where I get stuck. The "current connection" is tied to these
two values and they need to be injected into the FTPConnection.
If it was a web app, I might scope these values to the session but what if
I wanted to process all of them at once, in multiple threads?
The pseudo-code I'd like to write is this:
foreach( pair<UserInfo,ServerInfo> config : whatever() )
{
makeNewThreadAndProcessThisSite(config);
}
This is a very simplified view of the whole thing. I probably will not
write code like this but I think it's an approximate proxy for the problem
I am really trying to solve.
Would you kindly help me tease out a solution?
Thanks!
