Osservazioni

A condition is a logical expression that specifies a set of allowed states of a management facet on the target object. The facet is assigned to the condition using the Facet property and the allowed state is applied using a logical expression, specified by the ExpressionNode property. The Transact-SQL expression is assigned to the ExpressionNode object using the Parse(String) method.

Using a Condition object you can:

• Create, view, modify and delete a condition.

• Specify facets and expressions.

• Validate the condition.

• Discover the dependencies of the condition.

• Enumerate the policies that use the condition.
