Detailed Description

namespace holding expression classifier types and methods.

There are two basic categories of symbols in this namespace

• classifier() functions that determine what kind of expression is passed to them.

• data types whose sole purpose is to distinguish from another.

The classifier functions return different return value types based on what kind of expression is passed to them.

Function Documentation

classification< typename deconstify<T>::type >::printableClass fmtio::printableType::classifier

(

T const &

t

)

The template function, classifier<T>, returns a different type based on its parameter.

It does this only because specializations for all builtin data types, change the default classification::printableClass data type, UserDefined, to one of the well known types (Integral, String, etc.).

Parameters:

t

specifies a reference to some expression value

Returns:

a data type that implies the printing algorithm for value
