air.net.SecureSocketMonitor - Adobe® Flex® 4 Language Reference (Flex 4)

Package	air.net
Class	public class SecureSocketMonitor
Inheritance	SecureSocketMonitor SocketMonitor ServiceMonitor EventDispatcher Object

Runtime Versions:

AIR 2.0

A SecureSocketMonitor object monitors availablity of a TCP endpoint over Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols.

This class is included in the aircore.swc file. Flash Builder loads this class automatically when you create a project for AIR. The Flex SDK also includes this aircore.swc file, which you should include when compiling the application if you are using Flex SDK.

In Adobe^® Flash^® CS3 Professional, this class is included in the ServiceMonitorShim.swc file. To use classes in the air.net package , you must first drag the ServiceMonitorShim component from the Components panel to the Library and then add the following import statement to your ActionScript 3.0 code:

import air.net.*;

To use air.net package in Adobe^® Flash^® Professional (CS4 or higher):

Select the File > Publish Settings command.
In the Flash panel, click the Settings button for ActionScript 3.0. Select Library Path.
Click the Browse to SWC File button. Browse to Adobe Flash CSn/AIKn.n/frameworks/libs/air/aircore.swc file in the Adobe Flash Professional installation folder.
Click the OK button.
Add the following import statement to your ActionScript 3.0 code: import air.net.*;

	Property		Defined By
		available : Boolean Whether the service is currently considered "available." The initial value is false until either a status check sets the property to true or the property is initialized to true explicitly. Typically, this property is set by the checkStatus() implementation in a subclass or specializer, but if the application has independent information about a service's availability (for example, a request just succeeded or failed), the property can be set explicitly.	ServiceMonitor
		constructor : Object A reference to the class object or constructor function for a given object instance.	Object
		host : String [read-only] The host being monitored.	SocketMonitor
		lastStatusUpdate : Date [read-only] The time of the last status update.	ServiceMonitor
		pollInterval : Number The interval, in milliseconds, for polling the server.	ServiceMonitor
		port : int [read-only] The port being monitored.	SocketMonitor
		prototype : Object [static] A reference to the prototype object of a class or function object.	Object
		running : Boolean [read-only] Whether the monitor has been started.	ServiceMonitor

Constructor Detail

SecureSocketMonitor

()

Constructor

public function SecureSocketMonitor(host:String, port:int)

Runtime Versions:

AIR 2.0

Creates a SecureSocketMonitor object for a specified TCP endpoint.

After creating a SecureSocketMonitor object, the caller should call start to begin monitoring the status of the service.

As with the Timer object, the caller should maintain a reference to the SecureSocketMonitor object. Otherwise, the runtime deletes the object and monitoring ends.

Parameters

	`host:String` — The host to monitor.

	`port:int` — The port to monitor.

Method Detail

createSocket

()

method

override protected function createSocket():Socket

Runtime Versions:

AIR 2.0

Creates a SecureSocket object.

Returns

Socket — SecureSocket the SecureSocket object to be used by this SocketMonitor or null if secure sockets are not supported on the current system.

toString

()

method

override public function toString():String

Runtime Versions:

AIR 2.0

Returns the string representation of the specified object.

Note: Methods of the Object class are dynamically created on Object's prototype. To redefine this method in a subclass of Object, do not use the override keyword. For example, a subclass of Object implements function toString():String instead of using an override of the base class.

Returns

String — A string representation of the object.
