NAME

       Mason::Plugin::Cache - Provide component cache object and filter

VERSION

       version 0.05

SYNOPSIS

           my $result = $.cache->get('key');
           if (!defined($result)) {
               ... compute $result ...
               $.cache->set('key', $result, '5 minutes');
           }

           ...

           % $.Cache('key2', '1 hour') {{
             <!-- this will be cached for an hour -->
           % }}

DESCRIPTION

       Adds a "cache" method and "Cache" filter to access a cache (CHI) object with a namespace
       unique to the component.

INTERP PARAMETERS

       cache_defaults
           Hash of parameters passed to cache constructor. Defaults to

               driver=>'File', root_dir => 'DATA_DIR/cache'

           which will create a basic file cache under Mason's data directory.

       cache_root_class
           Class used to create a cache. Defaults to CHI.

COMPONENT CLASS METHODS

       cache
           Returns a new cache object with the namespace set to the component's path.  Parameters
           to this method, if any, are combined with cache_defaults and passed to the
           cache_root_class constructor.  The cache object is memoized when no parameters are
           passed.

               my $result = $.cache->get('key');

REQUEST METHODS

       cache
           Same as calling "cache" on the current component class. This usage will be familiar to
           Mason 1 users.

               my $result = $m->cache->get('key');

FILTERS

       Cache ($key, $options, [%cache_params])
           Caches the content using "$self->cache" and the supplied cache $key.

           $options is a scalar or hash reference. If a scalar, it is treated as the "expires_in"
           duration and passed as the third argument to "set". If it is a hash reference, it may
           contain name/value pairs for both "get" and "set".

           %cache_params, if any, are passed to "$self->cache".

               % $.Cache($my_key, '1 hour') {{
                 <!-- this will be cached for an hour -->
               % }}

               % $.Cache($my_key, { expire_if => sub { $.refresh } }, driver => 'RawMemory') {{
                 <!-- this will be cached until $.refresh is true -->
               % }}

           If neither $key nor $options are passed, the key is set to 'Default' and the cache
           never expires.

               % $.Cache() {{
                 <!-- cache this forever, or until explicitly removed -->
               % }}
