Synopsis

template <typename F>
inline typename make_unfused<F>::type
make_unfused(F const & f);

Parameters

Parameter	Requirement	Description
`f`	Model of Polymorphic Function Object	The function to transform.

Expression Semantics

make_unfused(f);

Return type: A specialization of unfused.

Semantics: Returns a unfused adapter for f.

Example

struct fused_incrementer
{
    template <class Seq>
    struct result
    {
        typedef void type;
    };

    template <class Seq>
    void operator()(Seq const & s) const
    {
        for_each(s,++boost::lambda::_1);
    }
};

void try_it()
{
    int a = 2; char b = 'X';
    make_unfused(fused_incrementer())(a,b);
    assert(a == 3 && b == 'Y');
