NAME

Data::Utilities - General utilities for nested perl data structures.

SYNOPSIS

    use Data::Utilities;

    my $tree
        = {
           a1 => {
                  a1 => '-a11',
                  a2 => '-a12',
                 },
           a2 => {
                  a1 => '-a21',
                  a2 => '-a22',
                 },
          };

    my $expected_data
        = {
           a1 => {
                  a2 => '-a12',
                 },
          };

    my $transformation
        = Data::Transformator->new
            (
             apply_identity_transformation => {
                                               a1 => {
                                                      a2 => 1,
                                                     },
                                              },
             contents => $tree,
             name => 'test_transform5',
            );

    my $transformed_data = $transformation->transform();

    use Data::Dumper;

    print Dumper($transformed_data);

    my $differences = data_comparator($transformed_data, $expected_data);

    if ($differences->is_empty())
    {
        print "$0: extraction ok\n";
    }
    else
    {
        print "$0: extraction failed\n";
    }

DESCRIPTION

Data::Utilities contains general tools to transform, merge, compare nested perl data structures. See the documentation of the modules in this package as indicated below.

USAGE

There are more documentation comments in Data::Transformator, for the moment I have no time to write better documentation than this. The best way to learn how to use it, is to take a look at the test cases.

The Neurospaces project (http://www.neurospaces.org/) makes heavy use of these utilities. So you can find some examples overthere to, especially in the test framework.
