Constructor Detail

HttpProtocolFinderThread

public HttpProtocolFinderThread(UploadPolicy uploadPolicy,
                                String givenServerProtocol)

Parameters:

uploadPolicy - The current upload policy

givenServerProtocol - The protocol given as parameter. If valid it will be used. If not, the serverProtocol will be computed from the post URL (and from a HEAD request for HTTP URL).

Method Detail

computeServerProtocol

public static void computeServerProtocol(UploadPolicy uploadPolicy,
                                         String givenServerProtocol)

This static method is the entry point for this class. It creates a thread, and launch it, returning immediately. The finding of the server protocol is then executed in a separated thread. So whenever long it is, the user won't see it. A default protocol is set immediately, in the run method, to be sure that there will be no NullPointerException.

Parameters:

uploadPolicy - The current upload policy

givenServerProtocol - The protocol given as parameter. If valid it will be used. If not, the serverProtocol will be computed from the post URL (and from a HEAD request for HTTP URL).

run

public void run()

The job itself. Will do a HEAD request if it's a HTTP URL. Will just note ftp if FTP. Otherwise: will throw an error.

Specified by:

run in interface Runnable

Overrides:

run in class Thread
