TargetSet Class

 

Applies To: SQL Server 2016 Preview

The TargetSet object represents a policy-based Management target set that holds information about levels, the condition for each level, and the target types.

Namespace:   Microsoft.SqlServer.Management.Dmf
Assembly:  Microsoft.SqlServer.Dmf (in Microsoft.SqlServer.Dmf.dll)

A target object set is the resulting set of target object after applying a filter to SQL Server instance. Using a T:System.Filter object you can create a T:Microsoft.SqlServer.Management.Sdk.SFC.Urn object which you can use to create an XPath expression. The XPath expression can be used to specify a skeleton XPath expression which filters the target objects out of the object set.

Legacy Code Example

C#

SFC.Urn urn = new SFC.Urn(filter);
SFC.XPathExpression xpe = urn.XPathExpression;

string ts_skeleton = urn.XPathExpression.ExpressionSkeleton;
ObjectSet os = new ObjectSet(p.Parent, p.Name + "ObjectSet");
os.Facet = p.Parent.Conditions[p.Condition].Facet;
TargetSet ts = os.TargetSets[ts_skeleton];
ts.Enabled = true;
for (int i = 1; i < xpe.Length; i++)
{
   if (null != xpe[i].Filter)
   {
      string skeleton = urn.XPathExpression.BlockExpressionSkeleton(i);
      TargetSetLevel cr = ts.GetLevel(skeleton);

      ExpressionNode expr = ExpressionNode.ConvertFromFilterNode(xpe[i].Filter);
      Condition c = ConditionObject.Create(p.Parent, cr.TargetType.Name, expr);
      ts.SetLevelCondition(cr, c.Name);
   }
}
os.Create();
p.ObjectSet = os.Name;

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
