returns a

context.
Override this method to coordinate with other transactors.
Override this method to coordinate with other transactors. The other transactors are added to the coordinated transaction barrier and sent a Coordinated message. The message to send can be specified or otherwise the same message as received is sent. Use the 'include' and 'sendTo' methods to easily create the set of transactors to be involved.
