RetrieveMetadataChangesResponse initialRequest = getMetadataChanges(entityQueryExpression, null, DeletedMetadataFilters.OptionSet);
   
   
   ...
   
   
   
protected RetrieveMetadataChangesResponse getMetadataChanges(
 EntityQueryExpression entityQueryExpression,
 String clientVersionStamp,
 DeletedMetadataFilters deletedMetadataFilter)
{
 RetrieveMetadataChangesRequest retrieveMetadataChangesRequest = new RetrieveMetadataChangesRequest()
