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.
