The ObjectSet type exposes the following members.

Constructors

  Name Description
Public method ObjectSet() Initializes a new instance of the ObjectSet class.
Public method ObjectSet(PolicyStore, String) Initializes a new instance of the ObjectSet class that has the specified parent policy store and the specified name.

Public property Facet Gets or sets the facet value for the object set.
Public property ID Gets the ID value that uniquely identifies the object set.
Public property IdentityKey Gets the SfcKey object.
Public property IsSystemObject Determines whether the ObjectSet is a Object.
Public property Metadata Returns metadata about the instance and its domain. (Inherited from SfcInstance.)
Public property Name Gets the name of the object set.
Public property Parent Gets or sets the parent of the ObjectSet object.
Public property Properties Returns a collection instance properties. (Inherited from SfcInstance.)
Protected property State Returns the state of the SfcInstance object. (Inherited from SfcInstance.)
Public property TargetSets Gets the TargetSetCollection.

Remarks

A target object set is the resulting set of target objects after applying a filter to an instance of SQL Server. 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;
