class PingService extends AdminWorkflowService with FlagCloseable with HasCloseContext with NamedLogging
Implements the core of the ledger ping service for a participant. The service measures the time needed for a nanobot on the responder to act on a contract created by the initiator.
The main functionality: 1. once instantiated, it automatically starts a Scala Nanobot that responds to pings for this participant 2. it provides a ping method that sends a ping to the given (target) party

Use this method to create a PromiseUnlessShutdown that will automatically be cancelled when the close context is closed.
Use this method to create a PromiseUnlessShutdown that will automatically be cancelled when the close context is closed. This allows proper clean up of stray promises when the node is transitioning to a passive state.
Note: you should *not* invoke
successon the returned promise but rather usetrySuccess. The reason is that the call tosuccessmay fail in case of shutdown.- Definition Classes
