Class template any_member_hook

boost::intrusive::any_member_hook

Synopsis

// In header: <boost/intrusive/any_hook.hpp>

template< Options> 
class any_member_hook : public  {
public:
  // construct/copy/destruct
  () ;
  (any_member_hook &) ;
  any_member_hook & (any_member_hook &) ;
  ~();

  // public member functions
   () ;
};

Description

Store this hook in a class to be inserted in an intrusive container.

The hook admits the following options: void_pointer<> and link_mode<>.

link_mode<> will specify the linking mode of the hook (normal_link or safe_link).

void_pointer<> is the pointer type that will be used internally in the hook and the container configured to use this hook.

any_member_hook public construct/copy/destruct

  1. () ;

    Effects: If link_mode is or safe_link initializes the node to an unlinked state.

    Throws: Nothing.

  2. (any_member_hook &) ;

    Effects: If link_mode is or safe_link initializes the node to an unlinked state. The argument is ignored.

    Throws: Nothing.

    Rationale: Providing a copy-constructor makes classes using the hook STL-compliant without forcing the user to do some additional work. swap can be used to emulate move-semantics.

  3. any_member_hook & (any_member_hook &) ;

    Effects: Empty function. The argument is ignored.

    Throws: Nothing.

    Rationale: Providing an assignment operator makes classes using the hook STL-compliant without forcing the user to do some additional work. swap can be used to emulate move-semantics.

  4. ~();

    Effects: If link_mode is normal_link, the destructor does nothing (ie. no code is generated). If link_mode is safe_link and the object is stored in a container an assertion is raised.

    Throws: Nothing.

any_member_hook public member functions

  1.  () ;

    Precondition: link_mode must be safe_link.

    Returns: true, if the node belongs to a container, false otherwise. This function can be used to test whether container::iterator_to will return a valid iterator.

    Complexity: Constant
