Abstract methods
Stream of events for paths that have been registered or watched.
Stream of events for paths that have been registered or watched.
Value parameters
- pollTimeout
-
amount of time for which the underlying platform is polled for events
Attributes
- Source
- Watcher.scala
Registers for events on the specified path.
Registers for events on the specified path.
This is a low-level abstraction on the platform's Path#register
. The supplied path must be a directory and events are raised for only direct descendants of the path. Use watch for a higher level API.
Returns a cancellation task that unregisters the path for events. Unregistration is optional - the Watcher
will free all resources when it is finalized. Unregistration is only needed when a Watcher
will continue to be used after unregistration.
Value parameters
- modifiers
-
modifiers to pass to the underlying
WatchService
when registering - path
-
directory to watch for events
- types
-
event types to register for; if
Nil
, all standard event types are registered
Attributes

-
unregistration task

- Watcher.scala
Registers for events on the specified path.
Registers for events on the specified path.
This is more feature-rich than the JVM's Path#register
. The supplied path may be a file or directory and events may raised for all descendants of the path. Use register for a lower-level API.
Returns a cancellation task that unregisters the path for events. Unregistration is optional - the Watcher
will free all resources when it is finalized. Unregistration is only needed when a Watcher
will continue to be used after unregistration.
