NAME

Jifty::CAS::Blob - An object in Jifty's content-addressed store

SYNOPSIS

   my $blob = Jifty::CAS->retrieve('js', $key);
   my $content = $blob->content;
   my $meta = $blob->metadata;
   my $key = $blob->key;
 
 

DESCRIPTION

Objects in the content-addressed store can have arbitrary metadata associated with them, in addition to storing their contents.

METHODS

new HASHREF

Takes a HASHREF, with possible keys ``content'' and ``metadata'', and creates a new object. Possible special keys in the metadata include:

hash_with

Provides the data to hash to generate the address. If no "hash_with" is provided, the content itself is hashed.

deflate

If set to a true value, deflates the content using ``memGzip'' in Compress::Zlib, and stores that in ``content_deflated''.

content

Returns the content of the blob.

content_deflated

If ``deflate'' in the metadata was set, contains the deflated content.

metadata

Returns a hashref of metadata.

key

Retuens the key calculated for this content.
