NAME ^

Bubblegum::Object::Universal - Common Methods for Operating on Defined Values

VERSION ^

version 0.45

SYNOPSIS ^

    use Bubblegum;

    my $thing = 0;
    $thing->instance; # bless({'data' => 0}, 'Bubblegum::Object::Instance')

DESCRIPTION ^

Universal methods work on variables whose data meets the criteria for being defined. It is not necessary to use this module as it is loaded automatically by the Bubblegum class.

METHODS ^

digest

    my $thing = '...';
    $thing->digest; # bless({'data' => '...'}, 'Bubblegum::Wrapper::Digest')

    my $data = $thing->digest->data;

The digest method blesses the subject into the wrapper class, Bubblegum::Wrapper::Digest, and returns an instance. Please see Bubblegum::Wrapper::Digest for more information.

dumper

    my $thing = '...';
    $thing->dumper; # bless({'data' => '...'}, 'Bubblegum::Wrapper::Dumper')

    my $data = $thing->dumper->data;

The dumper method blesses the subject into the wrapper class, Bubblegum::Wrapper::Dumper, and returns an instance. Please see Bubblegum::Wrapper::Dumper for more information.

encoder

    my $thing = '...';
    $thing->encoder; # bless({'data' => '...'}, 'Bubblegum::Wrapper::Encoder')

    my $data = $thing->encoder->data;

The encoder method blesses the subject into the wrapper class, Bubblegum::Wrapper::Encoder, and returns an instance. Please see Bubblegum::Wrapper::Encoder for more information.

instance

    my $thing = 0;
    $thing->instance; # bless({'data' => 0}, 'Bubblegum::Object::Instance')

    my $data = $thing->instance->data;

The instance method blesses the subject into a generic container class, Bubblegum::Object::Instance, and returns an instance. Please see Bubblegum::Object::Instance for more information.

json

    my $json = $thing->json->encode;

The wrapper method blesses the subject into a Bubblegum wrapper, a container class, which exists as an extension to the core data type methods, and returns an instance. Please see any one of the core Bubblegum wrappers, e.g., Bubblegum::Wrapper::Digest, Bubblegum::Wrapper::Dumper, Bubblegum::Wrapper::Encoder, Bubblegum::Wrapper::Json or Bubblegum::Wrapper::Yaml.
