Method Detail

onSynchronizationStart

void onSynchronizationStart(@Nullable
                            @Nullable String processingIdentifier,
                            @Nullable
                            @Nullable String shadowOid,
                            @Nullable
                            @Nullable SynchronizationSituationType situation)

Called when a situation was determined right before a synchronization takes place. We assume that we have a shadow with OID by that time. (If the OID is null we ignore further synchronization situation updates.)

onSynchronizationExclusion

void onSynchronizationExclusion(@Nullable
                                @Nullable String processingIdentifier,
                                @NotNull
                                @NotNull SynchronizationExclusionReasonType exclusionReason)

Informs the task that no synchronization will take place. Note that in theory it is possible that onSynchronizationStart(String, String, SynchronizationSituationType) is called first.

onSynchronizationSituationChange

void onSynchronizationSituationChange(@Nullable
                                      @Nullable String processingIdentifier,
                                      @Nullable
                                      @Nullable String shadowOid,
                                      @Nullable
                                      @Nullable SynchronizationSituationType situation)

Informs the task that sync situation has changed for given shadow OID. There could be more such changes. But we are interested in the last one. If the shadow OID is null, we ignore such updates.

startCollectingSynchronizationStatistics
```
void startCollectingSynchronizationStatistics(SynchronizationStatisticsCollector collector)
```
Starts collecting synchronization statistics within the task. Must be accompanied by corresponding stopCollectingSynchronizationStatistics(QualifiedItemProcessingOutcomeType) call. (Related to the same item!)

stopCollectingSynchronizationStatistics

void stopCollectingSynchronizationStatistics(@NotNull
                                             @NotNull QualifiedItemProcessingOutcomeType outcome)
