Method Detail

startWatching

@Nonnull
public Issue startWatching(@Nonnull
                                    ApplicationUser user,
                                    @Nonnull
                                    Issue issue)

Description copied from interface: WatcherManager

Enable watching of a particular issue for the user supplied.

This means the user will receive updates for any modifications to the issue. Note, that this will not check if a user has the BROWSE_ISSUE permission. Notifications will however only be sent to users who have the appropriate permissions. Adding a permission check here would complicate updating permission schemes a lot, as it would have to update issue's watchers lists.

Specified by:

startWatching in interface WatcherManager

Parameters:

user - user that starts watching the given issue

issue - issue being watched

Returns:

updated issue

startWatching

@Nonnull
public Collection<Issue> startWatching(@Nonnull
                                                ApplicationUser user,
                                                @Nonnull
                                                Collection<Issue> issues,
                                                @Nonnull
                                                Context taskContext)

Description copied from interface: WatcherManager

Enable watching of a list of issues for the user supplied.

This means the user will receive updates for any modifications to the issues. Note, that this will not check if a user has the BROWSE_ISSUE permission. Notifications will however only be sent to users who have the appropriate permissions. Adding a permission check here would complicate updating permission schemes a lot, as it would have to update issues' watchers lists.

Specified by:

startWatching in interface WatcherManager

Parameters:

user - user that starts watching the given issues

issues - the list of issues to watch

taskContext - a context through which progress can be reported back

Returns:

the same list of issues (the same order) updated or not
