Description

Creates a unfused_generic adapter for a given, unary Polymorphic Function Object. The usual element conversion is applied to the target function.

Synopsis
template <typename F>
inline typename make_unfused_generic<F>::type
make_unfused_generic(F const & f);
Parameters

Parameter

Requirement

Description

f

Model of Polymorphic Function Object

The function to transform.

Expression Semantics
make_unfused_generic(f);

Return type: A specialization of unfused_generic.

Semantics: Returns a unfused_generic adapter for f.
