A connector which attaches to a previously running target VM.
Author:Gordon Hirsch
Since: 1.3
/** * A connector which attaches to a previously running target VM. * * @author Gordon Hirsch * @since 1.3 */
public interface AttachingConnector extends Connector {
Attaches to a running application and and returns a mirror of its VM.

The connector uses the given argument map in attaching the application. These arguments will include addressing information that identifies the VM. 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.

Params:
  • arguments – the argument map to be used in launching the VM.
Throws:
  • TransportTimeoutException – when the Connector encapsulates a transport that supports a timeout when attaching, a Argument representing a timeout has been set in the argument map, and a timeout occurs when trying to attach to the target VM.
  • IOException – when unable to attach. Specific exceptions are dependent on the Connector implementation in use.
  • IllegalConnectorArgumentsException – when one of the connector arguments is invalid.
Returns:the VirtualMachine mirror of the target VM.
