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.

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