ROOT::Detail::RFieldVisitor Class Reference

Abstract base class for classes implementing the visitor design pattern.

RFieldVisitor::VisitField() is invoked by RFieldBase::AcceptVisitor().

Example: creating a custom field visitor**

// 1. Define your visitor:
class MyVisitor : public RFieldVisitor {
public:
   // This is the only method you need to define. The others will default to calling this.
   // Only implement other methods if you need special logic for a specific field type.
   void VisitField(const ROOT::RFieldBase &field) final {
      // ... do custom logic here ...
   }
};
 
// 2. Use it:
const auto &field = reader->GetModel().GetConstFieldZero();
MyVisitor visitor;
visitor.VisitField(field);

As an example of a concrete use case, see Internal::RPrintSchemaVisitor.
