Properties

  Name Description
Protected property AbstractIdentityKey Do not reference this member directly in your code. It supports the SQL Server infrastructure. (Inherited from SfcInstance.)
Public property Enabled Gets or sets the Boolean value that specifies whether the target set is enabled.
Public property ID Gets the ID value that uniquely identifies the target set.
Public property IdentityKey Gets the key value that identifies the target set.
Public property Levels Represents a collection of TargetSetLevel objects. Each TargetSetLevel object represents a policy-based Management target set level.
Public property Metadata Returns metadata about the instance and its domain. (Inherited from SfcInstance.)
Public property Parent Gets the ObjectSet object that is the parent of the TargetSet object.
Public property Properties Returns a collection instance properties. (Inherited from SfcInstance.)
Public property RootLevel Gets the root level for the target set.
Protected property State Returns the state of the SfcInstance object. (Inherited from SfcInstance.)
Public property TargetType Gets the target type for the target set.
Public property TargetTypeSkeleton Gets the target type skeleton for the target set.
Public property Urn Returns the uniform resource name of the SfcInstance object. (Inherited from SfcInstance.)

Remarks

A target object set is the resulting set of target object after applying a filter to SQL Server instance. Using a Filter object you can create a 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.

Examples

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;

Thread Safety

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