Sawyer::CommandLine::AnyParser< T > Class Template Reference

Description

template<typename T>
class Sawyer::CommandLine::AnyParser< T >

Parses any argument as plain text.

This parser consumes the entire following string and then attempts to convert it to type T, or throw an std::runtime_error. This differs from most other parsers which consume only those characters they recognize. For instance:

* int i;
* anyParser(i);
*

The anyParser(i) will throw an error for a command line like -n123x, but the integerParser(i) will consume only the "123" and leave "x" alone (which is presumably the "-x" nestled short switch). The integerParser will also provide more informative error messages for overflows.

This parser is primarily intended for parsing arbitrary strings as std::string, and uses that type when no other type is provided by template argument or constructor argument.

The boost::lexical_cast package is used for the conversion, but boost::bad_lexical_cast exceptions are caught and rethrown as std::runtime_error as required by the ValueParser interface.

Constructor & Destructor Documentation

template<typename T >
Sawyer::CommandLine::AnyParser< T >::AnyParser ( )

Member Function Documentation

template<typename T >
static Ptr Sawyer::CommandLine::AnyParser< T >::instance ( )
inlinestatic

Allocating constructor.

Returns a pointer to a new AnyParser object. Uses will most likely want to use the anyParser factory instead, which requires less typing.

template<typename T >
static Ptr Sawyer::CommandLine::AnyParser< T >::instance ( const ValueSaver::Ptr valueSaver)
inlinestatic

Allocating constructor.

Returns a pointer to a new AnyParser object. Uses will most likely want to use the anyParser factory instead, which takes the same arguments, but requires less typing.
