question: private void addOperations ( Set < ClassOrInterfaceType > concreteClassTypes , VisibilityPredicate visibility , ReflectionPredicate reflectionPredicate ) { Set < TypedOperation > operationSet = new LinkedHashSet < > ( ) ; ReflectionManager mgr = new ReflectionManager ( visibility ) ; for ( ClassOrInterfaceType classType : concreteClassTypes ) { mgr . apply ( new OperationExtractor ( classType , operationSet , reflectionPredicate ) , classType . getRuntimeClass ( ) ) ; } for ( TypedOperation operation : operationSet ) { operations . add ( operation ) ; } }
target:  Iterates through a set of simple and instantiated class types and uses reflection to extract the operations that satisfy both the visibility and reflection predicates, and then adds them to the operation set of this model.
