A property rule contains statements in the form "IF Condition THEN Result" where the result is a scalar value determined by evaluating the conditions in the rule.
You must define at least one PropertyStatement using the PropertyStatements property or the PropertyRule(InputType,PropertyStatement[]) constructor. If you define multiple statements, the result of evaluating this rule is the result of the first statement with a matching Condition criteria, or NULL if no criteria is met.

The following example shows how to define a property rule that defines three properties: Few, Some, and Alot. It uses this property rule to define a subscription to events where Quantity equals 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();
