public interface LaunchingConnector extends Connector {
Launches an application and connects to its VM. Properties
of the launch (possibly including options,
main class, and arguments) are specified in
arguments
. The argument map associates argument name strings to instances of Argument
. The default argument map for a connector can be obtained through Connector.defaultArguments
. Argument map values can be changed, but map entries should not be added or deleted. A target VM launched by a launching connector is not guaranteed to be stable until after the VMStartEvent
has been received.
Important note: If a target VM is launched through this funcctions, its output and error streams must be read as it executes. These streams are available through the Process
object returned by VirtualMachine.process
. If the streams are not periodically read, the target VM will stop executing when the buffers for these streams are filled.
Params: - arguments – the argument map to be used in launching the VM.
Throws: - IOException – when unable to launch.
Specific exceptions are dependent on the Connector implementation
in use.
- IllegalConnectorArgumentsException – when one of the
connector arguments is invalid.
- VMStartException – when the VM was successfully launched, but
terminated with an error before a connection could be established.
Returns: the VirtualMachine
mirror of the target VM.
