NAME

DataStore::CAS::File - Object returned by DataStore::CAS describing a CAS entry

VERSION

version 0.020001

DESCRIPTION

These are bare minimal wrappers that essentially just curry a few parameters to later calls to 'open' (or possibly 'put').

All file objects will have the attributes described here, but other attributes or methods may exist for the storage engine you are using; see the documentation for your particular store.

ATTRIBUTES

store

Read-only attribute; Reference to the DataStore::CAS which created this file.

hash

Read-only attribute; The digest hash of the bytes of this file.

size

Read-only attribute; The length of the file, in bytes.

METHODS

open

  $handle= $file->open( %flags | \%flags )

A convenience method to call $file->store->open_file($file, \%flags).

IMPLEMENTATION

File objects are equipped with an AUTOLOAD which passes all unknown function calls to $file->store->_file_$METHODNAME($file, @_).

This allows stores to use the built-in File objects without a lot of delegation.

File objects also come with a DESTROY which calls $file->store->_file_destroy($file)
