public function PropertyStatement (
    condition : Condition, 
    result : Argument

Parameters

condition
The Condition object that represents the condition to evaluate. This parameter sets the Condition property.

result
The Argument object that represents the scalar result to return if the condition is met. This parameter sets Result property.

Example

The following example shows how to specify three properties: Few, Some, and Alot. Subscribers can use these properties when defining subscriptions.

// 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();
