Method Detail

getGroupStatus

public ProcessGroupStatus getGroupStatus(String groupId)

Returns the status of all components in the specified group. This request is not in the context of a user so the results will be unfiltered.

Specified by:

getGroupStatus in interface EventAccess

Parameters:

groupId - group id

Returns:

the component status

getGroupStatus

public ProcessGroupStatus getGroupStatus(String groupId,
                                         RepositoryStatusReport statusReport)

Returns the status for the components in the specified group with the specified report. This request is not in the context of a user so the results will be unfiltered.

Parameters:

groupId - group id

statusReport - report

Returns:

the component status

generateRepositoryStatusReport

protected RepositoryStatusReport generateRepositoryStatusReport()

getGroupStatus

ProcessGroupStatus getGroupStatus(ProcessGroup group,
                                  RepositoryStatusReport statusReport,
                                  Predicate<Authorizable> isAuthorized,
                                  int recursiveStatusDepth,
                                  int currentDepth)

Returns the status for the components in the specified group with the specified report. The results will be filtered by executing the specified predicate.

Parameters:

group - group id

statusReport - report

isAuthorized - is authorized check

recursiveStatusDepth - the number of levels deep we should recurse and still include the the processors' statuses, the groups' statuses, etc. in the returned ProcessGroupStatus

currentDepth - the current number of levels deep that we have recursed

Returns:

the component status
