Description

BOOST_FUSION_ADAPT_STRUCT is a macro that can be used to generate all the necessary boilerplate to make an arbitrary struct a model of Random Access Sequence.

Synopsis

BOOST_FUSION_ADAPT_STRUCT(
    struct_name,
    member_name0,
    member_name1,
    member_name2,
    ...
    )

// Without BOOST_PP_VARIADICS support :
BOOST_FUSION_ADAPT_STRUCT(
    struct_name,
    (member_type0, member_name0)
    (member_type1, member_name1)
    (auto, member_name2)
    ...
    )

Semantics

The above macro generates the necessary code to adapt struct_name as a model of Random Access Sequence.

The sequence of member_nameN, arguments or (member_typeN, member_nameN) pairs declares the type and names of each of the struct members that are part of the sequence.

When member_typeN is omitted or set to auto, the type is infered with Boost.TypeOf.

The macro should be used at global scope, and struct_name should be the fully namespace qualified name of the struct to be adapted.

Example: BOOST_FUSION_ADAPT_STRUCT

namespace demo
{
    struct employee
    {
        std::string name;
        int age;
    };
}

// demo::employee is now a Fusion sequence
BOOST_FUSION_ADAPT_STRUCT(
    demo::employee,
    name,
    age)

// Without BOOST_PP_VARIADICS support :
BOOST_FUSION_ADAPT_STRUCT(
    demo::employee,
    (auto, name)
    (auto, age)
)
