Method overview

void addMessageListener(in AString aMessage, in nsIFrameMessageListener aListener, [optional] in boolean listenWhenClosed);
void removeMessageListener(in AString aMessage, in nsIFrameMessageListener aListener);
void sendAsyncMessage(in AString aMessage, in AString json);

Methods

addMessageListener()

Adds a message listener to the local frame. This listener will receive messages sent from the remote frame.

void addMessageListener(
  in AString aMessage,
  in nsIFrameMessageListener aListener
  [optional in boolean listenWhenClosed
);
Parameters
aMessage
The name of the message for which to add a listener.
aListener
An object implementing nsIFrameMessageListener whose receiveMessage method will be called when the message is received.
listenWhenClosed
Default is false. Set to oo if you want to receive messages during the short period after a frame has been removed from the DOM and before its frame script has finished unloading. This parameter only has an effect for frame message managers in the main process. An alternative method to listen for death of frame script is to use message-manager-disconnect  observer: Observer Notifications :: Message Manager.

removeMessageListener()

Removes a message listener previously added by calling addMessageListener().

void removeMessageListener(
  in AString aMessage,
  in nsIFrameMessageListener aListener
);
Parameters
aMessage
The name of the message for which to remove a listener.
aListener
An object implementing nsIFrameMessageListener to stop receiving messages.

sendAsyncMessage()

Asynchronously sends a message to the listeners.

void sendAsyncMessage(
  in AString aMessage,
  in AString json
); 
Parameters
aMessage
The name of the message to send to the listeners.
json Optional
A JSON object containing data to be delivered to the listeners.
