Text::RecordParser::Object(3pm) User Contributed Perl Documentation Text::RecordParser::Object(3pm)NAME
Text::RecordParser::Object - read delimited text files as objects
SYNOPSIS
my $o = $p->fetchrow_object;
my $name = $o->name;
METHOD
new
Just call "fetchrow_object" on a Text::RecordParser object to instantiate an object.
DESCRIPTION
This module extends the idea of how you interact with delimited text files, allowing you to enforce field names and identify field aliases
easily. That is, if you are using the "fetchrow_hashref" method to read each line, you may misspell the hash key and introduce a bug in
your code. With this module, Perl will throw an error if you attempt to read a field not defined in the file's headers. Additionally, any
defined field aliases will be created as additional accessor methods.
As much as I like the full encapsulation of inside-out objects (e.g., as described in _Perl Best Practies_ by Damian Conway and provided by
Class::Std), I couldn't figure out a way to dynamically create the class at runtime. Besides, I figure this interface is only for those
who want to use the overhead of objects to enforce policy. If you use this module and still access the hash underneath the object, I can't
really help you.
