类
class	xgboost::IntrusivePtrCell
	用于将引用计数嵌入到客户端对象的辅助类。有关内存顺序的讨论，请参见 https://boost.ac.cn/doc/libs/1_74_0/doc/html/atomic/usage_examples.html。更多...
class	xgboost::IntrusivePtr< T >
	侵入式指针 (Intrusive Pointer) 的实现。一个智能指针，指向带有嵌入式引用计数器的对象。底层对象必须实现一个友元函数 IntrusivePtrRefCount()，该函数返回引用计数器（类型为 IntrusivePtrCell）。侵入式指针比 std::shared_ptr<> 更快：std::shared_ptr<> 会为引用计数器额外分配内存，而侵入式指针则不会。更多...
struct	xgboost::IntrusivePtr< T >::Hash
struct	std::hash< xgboost::IntrusivePtr< T > >

命名空间
	xgboost
	多目标树的核心数据结构。
	std

IntrusivePtrCell &	xgboost::IntrusivePtrRefCount (T const *ptr) noexcept
