NAME

Jifty::CAS - Jifty's Content-addressable storage facility

SYNOPSIS

   my $key = Jifty::CAS->publish('js' => 'all', $content,
                       { hash_with => $content, # default behaviour
                         content_type => 'application/x-javascript',
                         deflate => 1
                       });
 
   $ie_key = Jifty::CAS->publish('js' => 'ie-only', $ie_content,
                       { hash_with => $ie_content,
                         content_type => 'application/x-javascript',
                       });
 
   $key = Jifty::CAS->key('js', 'ie-only');
   my $blob = Jifty::CAS->retrieve('js', $key);
 
 

DESCRIPTION

Provides an in-memory "md5"-addressed content store. Content is stored under a ``domain'', and can be addressed using wither the ``key'', which is an "md5" sum, or the ``name'', which simply stores the most recent key provided with that name.

METHODS

publish DOMAIN NAME CONTENT METADATA

Publishes the given "CONTENT" at the address "DOMAIN" and "NAME". "METADATA" is an arbitrary hash; see Jifty::CAS::Blob for more. Returns the key.

key DOMAIN NAME

Returns the most recent key for the given pair of "DOMAIN" and "NAME", or undef if none such exists.

retrieve DOMAIN KEY

Returns a Jifty::CAS::Blob for the given pair of "DOMAIN" and "KEY", or undef if none such exists.
