NAME

    Data::Transpose - iterate, filter and validate data, and transpose to

    different field names

DESCRIPTION

    Caters to your needs for manipulating data by different operations,

    which are filtering records, iterating records, validating and

    transposing to different field names.

VERSION

    Version 0.0023

SYNOPSIS

        use warnings;

        use strict;

        

        use Data::Transpose::Prefix;

        use Data::Dumper;

        

        my $data = {

            first => 'John',

            last  => 'Doe',

            foo   => 'bar',

        };

        

        my $dtp = Data::Transpose::Prefix->new(prefix => 'user.');

        foreach my $needs_prefix ( qw(first last) ) {

            $dtp->field( $needs_prefix );

        }

        

        my $output = $dtp->transpose( $data );

        

        print Data::Dumper->Dump([$data, $output], [qw(data output)]);

    outputs:

        $data = {

                  'first' => 'John',

                  'last' => 'Doe',

                  'foo' => 'bar'

                };

        $output = {

                    'user.last' => 'Doe',

                    'user.first' => 'John',

                    'foo' => 'bar'

                  };

REFERENCE

    Validator

      Data::Transpose::Validator

    Iterator

      Data::Transpose::Iterator

METHODS

 new

    Parameters for the constructor are:

    unknown

      Determines how to treat fields in the input hash which are not known

      to the Data::Transpose object:

      fail

	The transpose operation fails.

      pass

	Unknown fields in the input hash appear in the output hash. This is

	the default behaviour.

      skip

	Unknown fields in the input hash don't appear in the output hash.

      This doesn't apply to the "transpose_object" method.

 field

    Add a new field object and return it:

        $tp->field('email');

 group

    Add a new group object and return it:

        $tp->group('fullname', $tp->field('firstname'), $tp->field('lastname'));

 transpose

    Transposes input:

       $new_record = $tp->transpose($orig_record);

 transpose_object

    Transposes an object into a hash reference.
