Parameters

• resolutionPolicy
  The policy to use for resolving conflicts.

• sourceChanges
  The batch of changes from the source provider.

• changeDataRetriever
  An object that can be used to retrieve item data from the source replica.

• destinationKnowledge
  The knowledge of the destination replica.

• destinationForgottenKnowledge
  The forgotten knowledge of the destination replica.

• changeApplierTarget
  The object that will be called to save changes and conflicts.

• syncSessionState
  State information about the current session.

• syncCallback
  Callbacks that will receive notifications about change application events.

Remarks

This method detects conflicts that occur between the changes sent in sourceChanges and the corresponding items in the destination replica. It resolves any conflicts according to the policy specified by resolutionPolicy. If it is necessary, this method then calls methods on changeApplierTarget to save changes to the destination replica and to save unresolved conflicts.

To get the destination version, this method calls TryGetDestinationVersion on changeApplierTarget for each item in sourceChanges.
