예

The following examples show how to use a SimpleLeafCondition to define the conditions that need to be met by an event in order for Notification Services to generate a notification for the subscriber:

// Create the NSInstance object.
NSInstance testInstance =
    new NSInstance("InventoryTrackerInstance");

// Create the NSApplication object.
NSApplication testApplication =
    new NSApplication(testInstance, "InventoryTracker");

// Define subscription properties
Subscription s = new Subscription(testApplication, "InventoryTrackerSubscriptions");
s.SubscriberId = "TestUser1";
s.Enabled = true;
s.RuleName = "InventoryTrackerRule";
s["DeviceName"] = "Work e-mail";
s["SubscriberLocale"] = "en-US";

// Define OrCondition
s.Condition = new OrCondition(
    new SimpleLeafCondition(new FieldValue("Quantity"),
        SimpleOperator.GreaterThanOrEqualTo,
        500),
    new SimpleLeafCondition(new FieldValue("Quantity"),
        SimpleOperator.LessThanOrEqualTo,
        35)
);

// Add subscription
s.Add();

' Create the NSInstance object.
Dim testInstance As New NSInstance("InventoryTrackerInstance")
 
' Create the NSApplication object.
Dim testApplication As _
    New NSApplication(testInstance, "InventoryTracker")
 
' Define subscription properties
Dim s As New Subscription( _
    testApplication, "InventoryTrackerSubscriptions")
s.SubscriberId = "TestUser1"
s.Enabled = True
s.RuleName = "InventoryTrackerRule"
s("DeviceName") = "Work e-mail"
s("SubscriberLocale") = "en-US"
 
' Define OrCondition
s.Condition = New OrCondition( _
    New SimpleLeafCondition( _
        New FieldValue("Quantity"), _
        SimpleOperator.GreaterThanOrEqualTo, _
        500), _
    New SimpleLeafCondition( _
        New FieldValue("Quantity"), _
        SimpleOperator.LessThanOrEqualTo, _
        35))
 
' Add subscription
s.Add()
