Description
Performs synchronous object delivery to a callback.
The NotifyObject method performs synchronous object delivery to a callback located in a client channel. NotifyObject returns True if the delivery was successful, False otherwise. Call NotifyObject with the ChannelName, ClientId, CallbackId, Msg, Response, and Timeout parameters.
ChannelName represents the name of the channel callback.
ClientId represents the identifier of the client channel callback.
CallbackId is a string representing the identifier of the callback.
Msg is a TObject containing the object to be broadcasted.
Response is a TObject containing the response from the channel callback.
Timeout represents the time-out interval in milliseconds. By default it is set to INFINITE.
