NAME

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

CONTENTS

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 plugin instead of a subclass.

CREATING A SUBCLASS

A subclass should look something like this:



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

    # put your modifications here

    1;



LETTING MASON KNOW ABOUT YOUR SUBCLASSES

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

    By naming convention

First, create a subclass of Mason itself:



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

    1;



and use that in place of 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



By constructor parameter

You can specify your subclasses via base_* parameters to 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 CUSTOM MASON CLASSES in Mason::Interp for a complete list.
