Quando sottoposto a override in una classe derivata, salva le informazioni sugli elementi coinvolti in un conflitto di vincoli.

Spazio dei nomi: Microsoft.Synchronization
Assembly: Microsoft.Synchronization (in microsoft.synchronization.dll)

Sintassi

'Dichiarazione

    conflictingChange As ItemChange, _
    conflictingItemId As SyncId, _

'Utilizzo
Dim instance As INotifyingChangeApplierTarget2

    SyncId conflictingItemId, 
    ConstraintConflictReason reason, 
    Object conflictingChangeData, 
    SyncKnowledge conflictingChangeKnowledge, 
    boolean temporary

    conflictingChange : ItemChange,

Parametri

• conflictingChange
  Metadati dell'elemento per la modifica in conflitto rispetto al provider di origine.

• conflictingItemId
  ID elemento dell'elemento nella replica di destinazione in conflitto con l'elemento specificato da conflictingChange.

• reason
  Motivo per cui si è verificato il conflitto.

• conflictingChangeData
  Dati dell'elemento per la modifica in conflitto.

• conflictingChangeKnowledge
  Conoscenza da acquisire se viene applicata questa modifica. Deve essere salvata con la modifica.

• temporary
  true se si tratta di un conflitto temporaneo. In caso contrario, false.

Osservazioni

Se la modifica rappresentata da questo conflitto viene applicata a una replica, è necessario combinare conflictingChangeKnowledge con la conoscenza di tale replica.

Esempio

Nell'esempio seguente viene mostrato come salvare un conflitto di vincoli temporaneo tramite un oggetto MemoryConflictLog.

public void SaveConstraintConflict(ItemChange conflictingChange, SyncId conflictingItemId, 
    ConstraintConflictReason reason, object conflictingChangeData, SyncKnowledge conflictingChangeKnowledge, 
    bool temporary)
{
    if (!temporary)
    {
        // The in-memory conflict log is used, so if a non-temporary conflict is saved, it's
        // an error.
        throw new NotImplementedException("SaveConstraintConflict can only save temporary conflicts.");
    }
    else
    {
        // For temporary conflicts, just pass on the data and let the conflict log handle it.
        _memConflictLog.SaveConstraintConflict(conflictingChange, conflictingItemId, reason, 
            conflictingChangeData, conflictingChangeKnowledge, temporary);
    }
}
