Detailed Description

template<typename T, typename CharType, typename Traits = std::char_traits<CharType>, typename Alloc = std::allocator<CharType>>
struct ookii::lexical_convert< T, CharType, Traits, Alloc >

Template class used to convert strings to strongly typed argument values.

This base template uses a stringstream to do the conversion, relying on stream extraction operator>> for the provided type. The template can be specialized to provide conversion of custom types.

Template Parameters

T	The type to convert to.
CharType	The character type used.
Traits	The character traits to use. Defaults to std::char_traits<CharType>.
Alloc	The allocator to use. Defaults to std::allocator<CharType>.
