Method Details

verify

public abstract void verify(LabelAtom label,
 Computer c,
 hudson.remoting.Channel channel,
 FilePath root,
 TaskListener listener)
                     throws IOException,
InterruptedException

Called before a Computer becomes online to verify if the label assignment is correct.

Parameters:

label - Label whose validity you'll check.

channel - This is the channel object to talk to the slave. (This is the same object returned by Computer.getChannel() once it's connected.

root - The directory where this slave stores files. The same as Node.getRootPath(), except that method returns null until the slave is connected. So this parameter is passed explicitly instead.

listener - This is connected to the launch log of the computer. Since this method is called synchronously from the thread that launches a computer, if this method performs a time-consuming operation, this listener should be notified of the progress. This is also a good listener for reporting problems.

Throws:

IOException - Exceptions will be recorded to the listener, and the computer will not become online.

InterruptedException - Exceptions will be recorded to the listener, and the computer will not become online.
