=head1 NAME

Term::Table::HashBase - Build hash based classes.

=head1 SYNOPSIS

A class:

    package My::Class;
    use strict;
    use warnings;

    # Generate 3 accessors
    use Term::Table::HashBase qw/foo -bar ^baz/;

    # Chance to initialize defaults
    sub init {
        my $self = shift;    # No other args
        $self->{+FOO} ||= "foo";
        $self->{+BAR} ||= "bar";
        $self->{+BAZ} ||= "baz";
    }

    sub print {
        print join ", " => map { $self->{$_} } FOO, BAR, BAZ;
    }

Subclass it

    package My::Subclass;
    use strict;
    use warnings;

    # Note, you should subclass before loading HashBase.
    use base 'My::Class';
    use Term::Table::HashBase qw/bat/;

    sub init {
        my $self = shift;

        # We get the constants from the base class for free.
        $self->{+FOO} ||= 'SubFoo';
        $self->{+BAT} ||= 'bat';

        $self->SUPER::init();
    }

use it:

    package main;
    use strict;
    use warnings;
    use My::Class;

    my $one = My::Class->new(foo => 'MyFoo', bar => 'MyBar');

    # Accessors!
    my $foo = $one->foo;    # 'MyFoo'
    my $bar = $one->bar;    # 'MyBar'
    my $baz = $one->baz;    # Defaulted to: 'baz'

    # Setters!
    $one->set_foo('A Foo');

    #'-bar' means read-only, so the setter will throw an exception (but is defined).
    $one->set_bar('A bar');

    # '^baz' means deprecated setter, this will warn about the setter being
    # deprecated.
    $one->set_baz('A Baz');

    $one->{+FOO} = 'xxx';

=head1 DESCRIPTION

This package is used to generate classes based on hashrefs. Using this class
will give you a C<new()> method, as well as generating accessors you request.
Generated accessors will be getters, C<set_ACCESSOR> setters will also be
generated for you. You also get constants for each accessor (all caps) which
return the key into the hash for that accessor. Single inheritance is also
supported.

=head1 THIS IS A BUNDLED COPY OF HASHBASE

This is a bundled copy of L<Object::HashBase>. This file was generated using
the
C</home/exodist/perl5/perlbrew/perls/main/bin/hashbase_inc.pl>
script.

=head1 METHODS

=head2 PROVIDED BY HASH BASE

=over 4

=item $it = $class->new(@VALUES)

Create a new instance using key/value pairs.

HashBase will not export C<new()> if there is already a C<new()> method in your
packages inheritance chain.

B<If you do not want this method you can define your own> you just have to
declare it before loading L<Term::Table::HashBase>.

    package My::Package;

    # predeclare new() so that HashBase does not give us one.
    sub new;

    use Term::Table::HashBase qw/foo bar baz/;

    # Now we define our own new method.
    sub new { ... }

This makes it so that HashBase sees that you have your own C<new()> method.
Alternatively you can define the method before loading HashBase instead of just
declaring it, but that scatters your use statements.

=back

=head2 HOOKS

=over 4

=item $self->init()

This gives you the chance to set some default values to your fields. The only
argument is C<$self> with its indexes already set from the constructor.

=back

=head1 ACCESSORS

To generate accessors you list them when using the module:

    use Term::Table::HashBase qw/foo/;

This will generate the following subs in your namespace:

=over 4

=item foo()

Getter, used to get the value of the C<foo> field.

=item set_foo()

Setter, used to set the value of the C<foo> field.

=item FOO()

Constant, returns the field C<foo>'s key into the class hashref. Subclasses will
also get this function as a constant, not simply a method, that means it is
copied into the subclass namespace.

The main reason for using these constants is to help avoid spelling mistakes
and similar typos. It will not help you if you forget to prefix the '+' though.

=back

=head1 SUBCLASSING

You can subclass an existing HashBase class.

    use base 'Another::HashBase::Class';
    use Term::Table::HashBase qw/foo bar baz/;

The base class is added to C<@ISA> for you, and all constants from base classes
are added to subclasses automatically.
