force the engine to go back to idle state, aborting anything it is doing.

note no sync success or failure would be called. all Weave Exchanges would be closed. TCP connections would not be touched further. no operation if we're already in idle state. not available in callbacks.

disable auto sync.

only available in idle state. not available in callbacks.

enable auto sync.

only available in idle state. discovery happens right away. not available in callbacks.

simple getter for the maximum number of contacts this engine is configured to store

simple getter for client state

extract the likelihood for persistent.

the result would only be valid after sync operation is completed, within callbacks of OnSyncSucceeded and OnSyncFailed. otherwise it's transient and might be the current Likelihood rather than the next one to be used.

simple getter for the server state

initialize this client.

not available in callbacks

initialize this coordinator.

initialize for the Server role must be called as the first function after object construction if the intention is to be a Time Sync Server.

not available in callbacks

Called by higher layer to multicast time change notification.

not available in callbacks.

Called by higher layer to indicate that we just finished a round of time sync with either any Server or through some reliable means like NTP.

Called by higher layer to indicate that we just finished a round of time sync with other local Coordinators.

stop the service, no matter which role it is playing.

This function must be called to properly reclaim resources allocated, before another call to any of the init functions can be made. not available in callbacks.

sync using existing contacts.

sync operation could fail if there is no valid contacts available. set aForceDiscoverAgain to true to force discovery immediately. only available in idle state. not available in callbacks.

sync using the given list of contacts.

existing contact list would be flushed. only available in idle state. not available in callbacks.

sync using the given TCP connection and associated encryption and key id.

caller must take ownership of the TCP connection after sync finishes. no callback would be overwritten for the TCP connection, as a new Weave Exchange would be created and callbacks set on top of that context only available in idle state. not available in callbacks.
