Class FeatureInspector<E extends PMMLException>

java.lang.Object

org.jpmml.model.visitors.AbstractVisitor

org.jpmml.evaluator.visitors.FeatureInspector<E>

All Implemented Interfaces:

Direct Known Subclasses:

InvalidFeatureInspector, UnsupportedFeatureInspector

public abstract class FeatureInspector<E extends PMMLException>
extends org.jpmml.model.visitors.AbstractSimpleVisitor

This class provides a skeletal implementation of class model inspectors.

Unlike evaluation, which takes place in "dynamic mode", the inspection takes place in "static mode". The inspector performs the full traversal of the specified class model object. Every problematic feature is reported in the form of an appropriate PMMLException instance. The class model object can be considered safe and sound if the list of exceptions stays empty.

Typical usage:

 static
 public <E extends PMMLException> void inspect(FeatureInspector<E> inspector){
   Visitable visitable = ...;

   try {
     inspector.applyTo(visitable);
   } catch(PMMLException pe){
     List<E> exceptions = inspector.getException();
   }
 }
