Interface ChangeHistoryCallback<T>

All Known Subinterfaces:

IssueStatusHistoryCallback

All Known Implementing Classes:

AbstractIssueHistoryStatusCallback, DaysInColumnCallback, FixVersionHistoryCallback, IssueColumnChangeCollector, IssueCycleTimeCollector

public interface ChangeHistoryCallback<T>

Generic callback for gathering change history information. When requesting a history, implementations will be called for every change that matches the given input. These calls are guaranteed to be in chronological order, but they are batched by value. This means that in practice, all changes for one value (e.g. one status or fix version) are returned before changes for the next value.

Method Summary

void	after(T value) Called after the change history for the given value has been processed, and before the next value will be processed.
void	before(T value) Called before the change history for the given value is processed
void	changedFrom(java.lang.Long issueId, java.lang.String issueKey, org.joda.time.DateTime changeTime, T value) Called for a change from a given previous value
void	changedTo(java.lang.Long issueId, java.lang.String issueKey, org.joda.time.DateTime changeTime, T value) Called for a change to a given new value
