ComputerListener
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.
preOnline
in class ComputerListener
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.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.ComputerListener.onOnline(Computer, TaskListener)
