## Constructor & Destructor Documentation

template<typename MemberBase , typename Member, typename Object>

openvrml::node_impl_util::ptr_to_polymorphic_mem_impl< MemberBase, Member, Object >::ptr_to_polymorphic_mem_impl | ( | Member Object::* | ptr_to_mem | ) | `[inline, explicit]`

Construct.

Parameters:

  `[in]` | ptr_to_mem | pointer-to-member.

template<typename MemberBase , typename Member , typename Object >

openvrml::node_impl_util::ptr_to_polymorphic_mem_impl< MemberBase, Member, Object >::~ptr_to_polymorphic_mem_impl | ( |  | ) | throw ()`[inline, virtual]`

Destroy.

Template Parameters:

  | MemberBase | the base type of the member.
  | Member | the concrete type of the member.
  | Object | the type that contains the member.

## Member Function Documentation

template<typename MemberBase , typename Member , typename Object>

MemberBase & openvrml::node_impl_util::ptr_to_polymorphic_mem_impl< MemberBase, Member, Object >::deref | ( | Object & | obj | ) | `[inline, virtual]`

Dereference.

Template Parameters:

  | MemberBase | the base type of the member.
  | Member | the concrete type of the member.
  | Object | the type that contains the member.

Returns:
  a reference to the base type of the member.

Implements openvrml::node_impl_util::ptr_to_polymorphic_mem< MemberBase, Object >.

template<typename MemberBase , typename Member , typename Object>

const MemberBase & openvrml::node_impl_util::ptr_to_polymorphic_mem_impl< MemberBase, Member, Object >::deref | ( | const Object & | obj | ) | `[inline, virtual]`

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Returns:
  a `const` reference to the base type of the member.

Implements openvrml::node_impl_util::ptr_to_polymorphic_mem< MemberBase, Object >.
