Documentation for the Simulator/DOVE demo
Purpose: To show how the event service can be used to as a media to
transport monitoring events including data.
Application: The events contain C++ structs with avionics information.
They are supllied by sensors of an avionic and are
consumed by an JAVA applet running on a different machine and/or
location. The collected metrics are displayed in
JAVA Beans.
Implementation: A C++ Supplier pushes events containing a
navigation or weapons struct to the Event Service.
The Event Service dispatches the events to any number of
Consumers which are implemented in JAVA. The JAVA
consumer extracts the data of the structs and dispatches
it to various display components.
For more informations refer to:
$TAO_ROOT/docs/releasenotes/index.html
Requirements:
C++ compiler, TAO environment, Visibroker 3.2 for JAVA
!!RELEASE CHANGES:
- Visibroker 3.2 instead of 3.1 (new naming conventions)
- No more customization of the RtecEventCommC.h file (bug is fixed)
- A different Weapons struct is now used, but it does not influence
the functionality.
Files:
Common:
ss - restart Naming Service, connect the Event Service and
Scheduling service with this Naming Service
NavWeap.idl - IDL definition of the Weapons and Navigation struct
README - this readme file

Makefile - Event Supplier Makefile
(Event_Con.cpp, Event_Con.h - Event Consumer for testing)
svc.conf - helper file
Consumer, DOVEBrowswer: (in directory $TAO_ROOT/orbsvcs/tests/Simulator/DOVEBrowser/)

Event Service
Supplier:
Event_Sup -ORBport 10040 -f MLF.dat -m 1000
// -m 1000 for 1000 events sent by the supplier
// -f MLF.dat to read scheduling data from this file as input
