 TaskListener listener)

Description copied from class: ComputerListener

Called before a Computer is marked online.

This enables you to do some work on all the agents as they get connected. Unlike ComputerListener.onOnline(Computer, TaskListener), a failure to carry out this function normally will prevent a computer from marked as online.

Overrides:

preOnline in class ComputerListener

Parameters:

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

root - The directory where this agent stores files. The same as Node.getRootPath(), except that method returns null until the agent 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.
