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

Description

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

Parses a non-negative integer and converts it to numeric type T.

Matches a non-negative integer in the mathematical sense in C++ decimal, octal, or hexadecimal format, and attempts to convert it to the type T. If the integer cannot be converted to type T then an std::range_error is thrown, which is most likely caught by higher layers of the library and converted to an std::runtime_error with additional information about the failure. The syntax is that which is recognized by the strtoull function except that a leading minus sign is not allowed (yes, strtoull parses negative numbers and returns them as unsigned), plus trailing white space.

Constructor & Destructor Documentation

template<typename T >
Sawyer::CommandLine::NonNegativeIntegerParser< T >::NonNegativeIntegerParser ( )
inlineprotected

Constructor for derived classes.

Non-subclass users should use instance instead.

Member Function Documentation

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

Allocating constructor.

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

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

Allocating constructor.

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