Class goog.net.xpc.CrossPageChannel

A communication channel between two documents from different domains. Provides asynchronous messaging.

Instance Method Summary
	`close()` Closes the channel.
	`createPeerIframe(!Element parentElm, ?Function= opt_configureIframeCb, boolean= opt_addCfgParam) ⇒ !HTMLIFrameElement` Creates the iframe containing the peer page in a specified parent element. This method does not connect the channel, connect() still has to be called separately.
	`createTransport_()` Creates the transport for this channel. Chooses from the available transport based on the user agent and the configuration.
	`deliver_(string serviceName, string payload, string= opt_origin)` Delivers messages to the appropriate service-handler.
	`determineTransportType_() ⇒ (goog.net.xpc.TransportTypes\|null\|undefined)` Determine which transport type to use for this channel / useragent.
	`disposeInternal()` Deletes or nulls out any references to COM objects, DOM nodes, or other disposable objects. Classes that extend {@code goog.Disposable} should override this method. Not reentrant. To avoid calling it twice, it must only be called from the subclass' {@code disposeInternal} method. Everywhere else the public {@code dispose} method must be used. For example: mypackage.MyClass = function() { goog.base(this); // Constructor logic specific to MyClass. ... }; goog.inherits(mypackage.MyClass, goog.Disposable); mypackage.MyClass.prototype.disposeInternal = function() { goog.base(this, 'disposeInternal'); // Dispose logic specific to MyClass. ... };
	`escapeServiceName_(string name) ⇒ string` Escape the user-provided service name for sending across the channel. This URL-encodes certain special characters so they don't conflict with delimiters used by some of the transports, and adds a special prefix if the name conflicts with the reserved transport service name. This is the opposite of {@link #unescapeServiceName_}.
	`getPeerConfiguration() ⇒ ?Object`
	`getRole() ⇒ number` Returns the role of this channel (either inner or outer).
	`getTransportName() ⇒ string` Returns the tranport name in use for this channel.
	`getTransportType() ⇒ number` Returns the transport type in use for this channel.
	`isMessageOriginAcceptable_(string= opt_origin) ⇒ boolean` Returns whether an incoming message with the given origin is acceptable. If an incoming request comes with a specified (non-empty) origin, and the PEER_HOSTNAME config parameter has also been provided, the two must match, or the message is unacceptable.
	`notifyConnected_()` Called by the transport when the channel is connected.
	`notifyTransportError_()` Called by the transport in case of an unrecoverable failure.
	`setPeerWindowObject(?Object peerWindowObject)` Sets the window object the foreign document resides in.
	`unescapeServiceName_(string name) ⇒ string` Unescape the escaped service name that was sent across the channel. This is the opposite of {@link #escapeServiceName_}.

Static Method Summary
	`disposeAll_()` Disposes all channels.
