Esempio
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()
