Notes
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.
Exemples
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;
