The ObjectSet type exposes the following members.

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

Public propertyFacetGets or sets the facet value for the object set.
Public propertyIDGets the ID value that uniquely identifies the object set.
Public propertyIdentityKeyGets the SfcKey object.
Public propertyIsSystemObjectDetermines whether the ObjectSet is a Object.
Public propertyMetadataReturns metadata about the instance and its domain. (Inherited from SfcInstance.)
Public propertyNameGets the name of the object set.
Public propertyParentGets or sets the parent of the ObjectSet object.
Public propertyPropertiesReturns a collection instance properties. (Inherited from SfcInstance.)
Protected propertyStateReturns the state of the SfcInstance object. (Inherited from SfcInstance.)

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.

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.
