Method Detail

onSyncItemProcessingStart
```
void onSyncItemProcessingStart(@NotNull
                               @NotNull String processingIdentifier,
                               @Nullable
                               @Nullable SynchronizationSituationType situationBefore)
```
Support method for recording sync operation in the new way. 1. Informs the collector that synchronization-sensitive item is going to be processed. 2. Establishes a filter that rejects any events having processing identifier different from this one.

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.

onSyncItemProcessingEnd

void onSyncItemProcessingEnd(@NotNull
                             @NotNull String processingIdentifier,
                             @NotNull
                             @NotNull QualifiedItemProcessingOutcomeType outcome)

Records the synchronization-related information into the statistics. Stops the watching.

resetSynchronizationInformation

void resetSynchronizationInformation(SynchronizationInformationType value)
