Note

The following example shows the use of a MetadataFilterExpression to return non-intersect, user-owned entities not found in a list of excluded entities.


     // An array SchemaName values for non-intersect, user-owned entities that should not be returned.
     String[] excludedEntities = {
"WorkflowLog",
"Template",
"CustomerOpportunityRole",
"Import",
"UserQueryVisualization",
"UserEntityInstanceData",
"ImportLog",
"RecurrenceRule",
"QuoteClose",
"UserForm",
"SharePointDocumentLocation",
"Queue",
"DuplicateRule",
"OpportunityClose",
"Workflow",
"RecurringAppointmentMaster",
"CustomerRelationship",

"PostFollow",
"ImportMap",

     //A filter expression to limit entities returned to non-intersect, user-owned entities not found in the list of excluded entities.
     MetadataFilterExpression EntityFilter = new MetadataFilterExpression(LogicalOperator.And);
     EntityFilter.Conditions.Add(new MetadataConditionExpression("IsIntersect", MetadataConditionOperator.Equals, false));
     EntityFilter.Conditions.Add(new MetadataConditionExpression("OwnershipType", MetadataConditionOperator.Equals, OwnershipTypes.UserOwned));
     EntityFilter.Conditions.Add(new MetadataConditionExpression("SchemaName", MetadataConditionOperator.NotIn, excludedEntities));
     MetadataConditionExpression isVisibileInMobileTrue = new MetadataConditionExpression("IsVisibleInMobile", MetadataConditionOperator.Equals, true);
     EntityFilter.Conditions.Add(isVisibileInMobileTrue);
