    Argument argument
)

BooleanLeafCondition (
    Argument^ argument
)

public function BooleanLeafCondition (
    argument : Argument
)

Parameters

argument
The Boolean-valued Argument to evaluate. This parameter sets the Argument property.

Example

Instead of checking a field or using a function, the condition in this example simply sets the Boolean value to true, resulting in notifications for all events. This could be used in an enterprise monitoring subscription or a subscription used to verify that the Notification Services application is generating notifications as expected:

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

// Define a condition that is true for all events.
s.Condition = new BooleanLeafCondition(true);

// Add subscription.
s.Add();
