BOOST_FUSION_ADAPT_STRUCT is a macro that can be used to generate all the

necessary boilerplate to make an arbitrary struct into a < a href = "../sequence/concepts/random_access_sequence.html" title = "Random

The above macro generates the necessary code to adapt < tt class = "computeroutput" > < span class = "identifier" > struct_name< / span > < / tt >
as a model of < a href = "../sequence/concepts/random_access_sequence.html" title = "Random
Access Sequence">Random
Access Sequence< / a > . The sequence of < tt class = "computeroutput" > < span class = "special" > (< / span > < span class = "identifier" > member_typeN< / span > < span class = "special" > ,< / span >
< span class = "identifier" > member_nameN< / span > < span class = "special" > )< / span > < / tt >
2007-12-21 03:13:31 +00:00
pairs declare the type and names of each of the struct members that will
be part of the sequence.

2008-07-08 02:43:21 +00:00
The macro should be used at global scope, and < tt class = "computeroutput" > < span class = "identifier" > struct_name< / span > < / tt >
2007-12-21 03:13:31 +00:00
should be the fully namespace qualified name of the struct to be converted.
