=head1 NAME

Mason::Manual::Subclasses - Creating custom subclasses of Mason's classes

=head1 DESCRIPTION

You can subclass the following Mason classes for your application:

    Mason::CodeCache
    Mason::Compilation
    Mason::Component
    Mason::Component::ClassMeta
    Mason::Component::Import
    Mason::Component::Moose
    Mason::Interp
    Mason::Request
    Mason::Result

and arrange things so that Mason always uses your subclass instead of its
default class.

Note: if you want to create a general purpose modification to Mason to use in
multiple applications, you should probably create a
L<plugin|Mason::Manual::Plugins> instead of a subclass.

=head1 CREATING A SUBCLASS

A subclass should look something like this:

    package My::Mason::Interp;
    use Moose;
    extends 'Mason::Interp';

    # put your modifications here

    1;

=head1 LETTING MASON KNOW ABOUT YOUR SUBCLASSES

There are two ways to let Mason know about your subclasses: by naming
convention, and by parameters to C<< Mason->new >>.

=head2 By naming convention

First, create a subclass of Mason itself:

    package My::Mason;
    use Moose;
    extends 'Mason';

    1;

and use that in place of C<< Mason >> in construction:

    my $interp = My::Mason->new();

Now, you can place any subclasses under 'My::Mason' and they'll automatically
be picked up. e.g.

    My::Mason::Compilation
    My::Mason::Interp
    My::Mason::Request

=head1 By constructor parameter

You can specify your subclasses via "base_*" parameters to C<< Mason->new() >>.
e.g.

    my $interp = Mason->new(
         base_compilation_class => 'My::Mason::Compilation',
         base_interp_class => 'My::Mason::Interp'
         base_request_class => 'Some::Other::Mason::Request'
    );

See L<Mason::Interp/CUSTOM MASON CLASSES> for a complete list.
