Detailed Description

template<typename>
class cppgc::GarbageCollected< typename >

Base class for managed objects. Only descendent types of GarbageCollected can be constructed using MakeGarbageCollected. Must be inherited from as left-most base class.

Types inheriting from GarbageCollected must provide a method of signature void Trace(cppgc::Visitor*) const that dispatchs all managed pointers to the visitor and delegates to garbage-collected base classes. The method must be virtual if the type is not directly a child of GarbageCollected and marked as final.

// Example using final class.
class FinalType final : public GarbageCollected<FinalType> {
 public:
  void Trace(cppgc::Visitor* visitor) const {
    // Dispatch using visitor->Trace(...);
  }
};
 
// Example using non-final base class.
class NonFinalBase : public GarbageCollected<NonFinalBase> {
 public:
  virtual void Trace(cppgc::Visitor*) const {}
};
 
class FinalChild final : public NonFinalBase {
 public:
  void Trace(cppgc::Visitor* visitor) const final {
    // Dispatch using visitor->Trace(...);
    NonFinalBase::Trace(visitor);
  }
};
