Developing your own Strategy Implementation

If you have custom requirements not met by the implementations included with the Engine, you may develop your own strategy implementation(s) for use in your products as follows:

• Add a new entry to DeterminationCompStrategy code table (using custom .ctx files);
• Create an implementation class which implements the DeterminationComparisonStrategy interface; implement the required method to return whether the two determinations passed in are considered to have equal data;
• Bind the code table entry to your implementation, in your custom Guice Module:

  {
    // Register your custom determination comparison strategies
    final MapBinder<DETERMINATIONCOMPARISONSTRATEGYEntry, 
                       DeterminationComparisonStrategy> 
      determinationComparisonStrategies
        = MapBinder.newMapBinder(binder(),
            DETERMINATIONCOMPARISONSTRATEGYEntry.class,
            DeterminationComparisonStrategy.class);
  
    determinationComparisonStrategies.addBinding(
      DETERMINATIONCOMPARISONSTRATEGYEntry.YOUR_STRATEGY.to(
        YourDeterminationComparisonStrategy.class));
  }

  (replacing YOUR_STRATEGY with the constant for your new code table code and YourDeterminationComparisonStrategy with your strategy implementation class as appropriate)

• Build your application;
• Configure your product to use your new strategy (see instructions above).
