Hi,

Is it possible to decompose boost::function into it's "constituent" parameters and return type, a la Boost.FunctionTypes?

http://www.boost.org/doc/libs/1_46_1/libs/type_traits/doc/html/boost_typetra...

Is this what you want?

Unfortunately not, that only works on "function types", the type of boost::function is some unspecified struct/class. Mostafa

Sure!

You can use function_types on the Signature that function was instantiated with:

http://www.boost.org/doc/libs/1_42_0/libs/function_types/doc/html/boost_func...

You can also access the member types within the function: http://www.boost.org/doc/libs/1_42_0/doc/html/boost/functionN.html

Thanks, I did consider that. But I am/was only interested in boost::function, because for some now forgotten (and maybe erroneous) reason I'd concluded that I did not have access to the signature that it was instantiated with. Mostafa
