Parses a positive integer and converts it to numeric type T
.
Matches a positive 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.

Allocating constructor.
Returns a pointer to a new PositiveIntegerParser object. Uses will most likely want to use the positiveIntegerParser factory instead, which requires less typing.
