Source Context:
// NOTE: The following is an Unreal extension to standard shared_ptr behavior 788 FORCEINLINE TSharedRef< ObjectType, Mode > ToSharedRef() const 789 { 790 // If this assert goes off, it means a shared reference was created from a shared pointer that was nullptr. 791 // Shared references are never allowed to be null. Consider using TSharedPtr instead. 792 check( IsValid() ); 793 ***** return TSharedRef< ObjectType, Mode >( *this ); 794 } 795
