NAME
Value::Object::Identifier - Value object class representing a legal C identifier
VERSION
This document describes Value::Object::Identifier version 0.07
SYNOPSIS
use Value::Object::Identifier;
my $ident = Value::Object::Identifier->new( 'foo' );
my $userident = Value::Object::Domain->new( $unsafe_identifier );
# We'll only get here if the $unsafe_identifier was a legal identifier
print "'", $userident->value, "' is a valid identifier.\n";DESCRIPTION
A Value::Object::Identifier value object represents a legal C identifier. This definition is actually used in more than just C. An identifier is limited to the ASCII uppercase and lowercase letters, the ASCII digits, and the underscore. The initial character of an identifier cannot be a digit. The C standard does not impose a length limit, so this class does not either. In actual use, there are a particular strings that are not allowed as identifiers (like C keywords). This class does not enforce that restriction.
If these criteria are not met, an exception is thrown.
