collectStatusHistory

public ServiceOutcome<java.lang.Void> collectStatusHistory(com.atlassian.crowd.embedded.api.User user,
                                                           com.atlassian.query.Query query,
                                                           IssueStatusHistoryCallback callback)

Read the status history from the Lucene history index. The index itself is having a very shallow document part: Documents only contain change date, issue ID and issue key. This means we can't query the index directly and read all we want from the documents in one pass, but rather have to use multiple passes for each status to find the matching changes. The results are being fed back into the provided callback implementation.

Specified by:

collectStatusHistory in interface IssueStatusHistoryService

Parameters:

user - : the user executing the query

query - : which issues do we want to look at

callback - : This will be informed of every status change found in the history.
