The documentation says:
The new subclass may require certain configuration information, which can be specified in the Network Configuration definition, read by the engine, and passed as a PropertyTree constructor argument to the new subclass
Also the other option is to get the PropertyTree on the message call itself. But I don’t know where to do that either? The documentation says:
Another example is in the facility to extend the metadata associated with each message to include additional metadata items not compiled into the engine (USERDATA)
Any one got any ideas?
thanks,
Matt
