T
- The type of the context object associated with the eventpublic interface WatchEvent<T>
An event or a repeated event for an object that is registered with a WatchService
.
An event is classified by its kind
and has a count
to indicate the number of times that the event has been observed. This allows for efficient representation of repeated events. The context
method returns any context associated with the event. In the case of a repeated event then the context is the same for all events.
Watch events are immutable and safe for use by multiple concurrent threads.
