Class DaysInColumnCallback

java.lang.Object
  com.atlassian.greenhopper.service.charts.AbstractIssueHistoryStatusCallback
      com.atlassian.greenhopper.web.rapid.list.DaysInColumnCallback

All Implemented Interfaces:

ChangeHistoryCallback<com.atlassian.jira.issue.status.Status>, IssueStatusHistoryCallback

public class DaysInColumnCallback
extends AbstractIssueHistoryStatusCallback

Collector to find out the total time an issue spent in the column it's currently in. The idea works like this: The query defines which issues we're looking into. We're sending that off to the history index, and collect the change history for every status. Then we aggregate the time spent per issue and fill it into the REST template.

Constructor Detail

DaysInColumnCallback

public DaysInColumnCallback(java.util.Map<java.lang.Long,RapidIssueEntry> issues,
                            java.util.Map<com.atlassian.jira.issue.status.Status,Column> columnsByStatus,
                            java.util.List<com.atlassian.jira.issue.status.Status> statuses)

Method Detail

getStatuses

public java.util.Collection<com.atlassian.jira.issue.status.Status> getStatuses()

Returns:

The statuses to query for. Callbacks will be for each status in the collection, for all issues according to getQuery(), in the order of the collection.

changedFrom

public void changedFrom(java.lang.Long issueId,
                        java.lang.String issueKey,
                        org.joda.time.DateTime changeTime,
                        com.atlassian.jira.issue.status.Status changedFromStatus)

Pick up changes from a status that's in the same column like the current issue status. These are the only ones we're interested in, all other status changes just get ignored. We only want to know how long the issue has been in the _current_ column.

Specified by:

changedFrom in interface ChangeHistoryCallback<com.atlassian.jira.issue.status.Status>

Overrides:

changedFrom in class AbstractIssueHistoryStatusCallback

changeTime - : time when the change was performed, in UTC

changedFromStatus - : the old value the issue has changed from (e.g. old status or version ID)

changedTo

public void changedTo(java.lang.Long issueId,
                      java.lang.String issueKey,
                      org.joda.time.DateTime changeTime,
                      com.atlassian.jira.issue.status.Status changedToStatus)

Same like above, but for changes into the column

Specified by:

changedTo in interface ChangeHistoryCallback<com.atlassian.jira.issue.status.Status>

Overrides:

changedTo in class AbstractIssueHistoryStatusCallback

changeTime - : time when the change was performed, in UTC

changedToStatus - : the new value (e.g. Status or fix version ID) the issue has changed to

after

public void after(com.atlassian.jira.issue.status.Status status)

We're done with one status, all changes to and from have been collected. Now we want "time in column", not "time in status", but that's just an additive. Basically, we only have collected data that relates to the current column, which makes things a little easier.

Specified by:

after in interface ChangeHistoryCallback<com.atlassian.jira.issue.status.Status>

Overrides:

after in class AbstractIssueHistoryStatusCallback
