  /**
   * This method is called from a messaging adapter to handle the delivery of messages to one or
   * more clients. If you pass in the <code>sendToAllSubscribers</code> parameter as <code>true
   * </code>, the message is routed to all clients who are subscribed to receive messages from this
   * destination. When you use this method, the selector expressions for all subscribing clients are
   * not evaluated. If you want the selector expressions to be evaluated, use a combination of the
   * <code>pushMessageToClients</code> method and the <code>sendPushMessageFromPeer</code> methods.
   *
   * @param message The <code>Message</code> to send.
   * @param sendToAllSubscribers If <code>true</code>, send this message to all clients subscribed
   *     to the destination of this message. If <code>false</code>, send the message only to the
   *     clientId specified in the message.
