NAME

       Dancer::Route::Cache - route caching mechanism for Dancer

SYNOPSIS

	   my $cache = Dancer::Route::Cache->new(
	       path_limit => 300, # optional
	   );

	   # storing a path
	   # /new/item/ is the path, $route is a compiled route
	   $cache->store_path( 'get', '/new/item/', $route );
	   my $cached_route = $cache->route_from_path('/new/item/');

DESCRIPTION

       When Dancer first starts, it has to compile a regexp list of all the routes.  Then, on each request it goes over the compiled routes list
       and tries to compare the requested path to a route.

       A major drawback is that Dancer has to go over the matching on every request, which (especially on CGI-based applications) can be very time
       consuming.

       The caching mechanism allows one to cache some requests to specific routes (but NOT specific results) and run those routes on a specific
       path. This allows us to speed up Dancer quite a lot.

METHODS
/SUBROUTINES
   new(@args)
       Creates a new route cache object.

	   my $cache = Dancer::Route::Cache->new(
	       path_limit => 100,   # only 100 paths will be cached
	       size_limit => '30M', # max size for cache is 30MB
	   );

       Please check the "ATTRIBUTES" section below to learn about the arguments for "new()".

   route_from_path($path)
       Fetches the route from the path in the cache.

   store_path( $method, $path => $route )
       Stores the route in the cache according to the path and $method.

       For developers: the reason we're using an object for this and not directly using the registry hash is because we need to enforce the
       limits.

   parse_size($size)
       Parses the size wanted to bytes. It can handle Kilobytes, Megabytes or Gigabytes.

       NOTICE: handles bytes, not bits!

	   my $bytes = $cache->parse_size('30M');

	   # doesn't need an existing object
	   $bytes = Dancer::Route::Cache->parse_size('300G'); # works this way too

   route_cache_size
       Returns a rough calculation the size of the cache. This is used to enforce the size limit.

   route_cache_paths
       Returns all the paths in the cache. This is used to enforce the path limit.

ATTRIBUTES

   size_limit($limit)
       Allows one to set a size limit of the cache.

       Returns the limit (post-set).

	   $cache->size_limit('10K');	   # sets limit
	   my $limit = $cache->size_limit; # gets limit

   path_limit($limit)
       A path limit. That is, the amount of paths that whose routes will be cached.

       Returns the limit (post-set).

	   $cache->path_limit('100');	   # sets limit
	   my $limit = $cache->path_limit; # gets limit
