Parámetros

• rule
  The RuleLogic instance that is evaluated to determine the value of the RuleValue instance.

Notas

The specified RuleLogic instance must have the same InputType value as the rule or condition you are defining.

A RuleLogic instance of type FilterRule has a Boolean return value; an instance of type PropertyRule has a return type determined by the Result property.

Ejemplo

The following example shows how to use a rule value to obtain the logic for a SimpleLeafCondition from a PropertyRule. The SimpleLeafCondition to evaluate the Quantity field for a value that matches the definition of Few:

// Define a new property that defines "Few," "Some," and "Alot"
// of inventory. 
PropertyRule quantityCategory = new PropertyRule(
    new ViewInputType(eventView),
    new PropertyStatement(new SimpleLeafCondition(
        new FieldValue("Quantity"),
        SimpleOperator.LessThan, 100), "Few"),
    new PropertyStatement(new BetweenLeafCondition(
        new FieldValue("Quantity"), 100, 200), "Some"),
    new PropertyStatement(new SimpleLeafCondition(
            new FieldValue("Quantity"),
            SimpleOperator.GreaterThan, 200),
        "Alot"));

// Create subscription and define basic properties.
s = new Subscription(nsApplication, subscriptionClassName);
s.SubscriberId = "Scott";
s.Enabled = true;
s.RuleName = "InventoryTrackerRule";
s.SetFieldValue("DeviceName", "myDevice");
s.SetFieldValue("SubscriberLocale", "en-us");


// Use the new property to return only products with "few" remaining
// in inventory. Note that the category definition can be reused.
s.Condition = new SimpleLeafCondition(
    new RuleValue(quantityCategory),
    SimpleOperator.Equals,
    "Few");

// Add subscription.
s.Add();
