Appendix: Using One Engine Per Configuration

This section briefly explains how to use one engine per configuration to meet the requirements outlined in this tutorial. The following code should only be run once when the application loads. For example, it could go into main().

// Declare your engines, one for Acme, and one for Magic.
HL7appEngine EngineAcme;
HL7appEngine EngineMagic;

// Load the VMD files for Acme and Magic.
Listener.EngineAcme.Load("after_adding_configuration.vmd");
Listener.EngineMagic.Load("after_adding_configuration.vmd");

// Set the configuration numbers.
Listener.EngineAcme.SetCurrentConfigurationIndex(0);
Listener.EngineMagic.SetCurrentConfigurationIndex(1);

//When a message comes in for Acme, use Listener.EngineAcme to parse it.
//When a message comes in for Magic, use Listener.EngineMagic to parse it.
