FAQ

How do I use the Expressional Inference Rule Engine programmatically?

To access the Expressional Inference Rule Engine in your code—for example, to infer a goal value using a rule document in either the authoring or delivery tier—use the following approach:

// Retrieve the InferenceEngine instance from the HippoServiceRegistry.
InferenceEngine inferEngine = HippoServiceRegistry.getService(InferenceEngine.class);
// In the delivery tier, you can also obtain it from the HstServices component manager:
inferEngine = HstServices.getComponentManager().getComponent(InferenceEngine.class.getName(), InferenceEngineModule.MODDULE_NAME);

if (inferEngine != null) {
  Object goalValue = inferEngine.executeInference(RULES_DEMO_VISITOR_INTEREST_TYPE);
}
copy

This example shows how to obtain the InferenceEngine and execute inference using a specific rule type.
