Fields
ENTRY_CREATE
public static final Kind<Path> ENTRY_CREATE
Directory entry created.
When a directory is registered for this event then the WatchKey
is queued when it is observed that an entry is created in the directory
or renamed into the directory. The event count
for this event is always 1.
ENTRY_DELETE
public static final Kind<Path> ENTRY_DELETE
Directory entry deleted.
When a directory is registered for this event then the WatchKey
is queued when it is observed that an entry is deleted or renamed out of
the directory. The event count for this event
is always 1.
ENTRY_MODIFY
public static final Kind<Path> ENTRY_MODIFY
Directory entry modified.
When a directory is registered for this event then the WatchKey
is queued when it is observed that an entry in the directory has been
modified. The event count for this event is
1 or greater.
OVERFLOW
public static final Kind<Object> OVERFLOW
A special event to indicate that events may have been lost or
discarded.
The context for this event is
implementation specific and may be null. The event count may be greater than 1.
