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 0.0022 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.
