File::DataClass - Structured data file IO with OO paradigm


This document describes version v0.27.$Rev: 1 $ of File::DataClass


   use File::DataClass::Schema;

   $schema = File::DataClass::Schema->new
      ( path    => [ qw(path to a file) ],
        result_source_attributes => { source_name => {}, },
        tempdir => [ qw(path to a directory) ] );

   $schema->source( q(source_name) )->attributes( [ qw(list of attr names) ] );
   $rs = $schema->resultset( q(source_name) );
   $result = $rs->find( { name => q(id of field element to find) } );
   $result->$attr_name( $some_new_value );
   @result = $rs->search( { 'attr name' => q(some value) } );


Provides methods for manipulating structured data stored in files of different formats

The documentation for this distribution starts in the class File::DataClass::Schema

File::DataClass::IO is a Moo based implementation of IO::Alls API. It implements the file and directory methods only

Configuration and Environment

Defines no attributes



   $hash_ref_of_CHI_objects = File::DataClass->F_DC_Cache;

A class method which returns a hash ref of CHI objects which are used to cache the results of reading files






On MSWin32 and Cygwin it is assumed that NTFS is being used and that it does not support mtime so caching on those platforms is disabled

Bugs and Limitations

There are no known bugs in this module. Please report problems to Patches are welcome


Larry Wall - For the Perl programming language

The class structure and API where taken from DBIx::Class

The API for the file IO was taken from IO::All
