Cache::FileCache - phpMan

NAME
    Cache::FileCache -- implements the Cache interface.

DESCRIPTION
    The FileCache class implements the Cache interface. This cache stores
    data in the filesystem so that it can be shared between processes.

SYNOPSIS
      use Cache::FileCache;

      my $cache = new Cache::FileCache( { 'namespace' => 'MyNamespace',
                                          'default_expires_in' => 600 } );

      See Cache::Cache for the usage synopsis.

METHODS
    See Cache::Cache for the API documentation.

    Clear( [$cache_root] )
        See Cache::Cache, with the optional *$cache_root* parameter.

    Purge( [$cache_root] )
        See Cache::Cache, with the optional *$cache_root* parameter.

    Size( [$cache_root] )
        See Cache::Cache, with the optional *$cache_root* parameter.

OPTIONS
    See Cache::Cache for standard options. Additionally, options are set by
    passing in a reference to a hash containing any of the following keys:

    *cache_root*
        The location in the filesystem that will hold the root of the cache.
        Defaults to the 'FileCache' under the OS default temp directory (
        often '/tmp' on UNIXes ) unless explicitly set.

    *cache_depth*
        The number of subdirectories deep to cache object item. This should
        be large enough that no cache directory has more than a few hundred
        objects. Defaults to 3 unless explicitly set.

    *directory_umask*
        The directories in the cache on the filesystem should be globally
        writable to allow for multiple users. While this is a potential
        security concern, the actual cache entries are written with the
        user's umask, thus reducing the risk of cache poisoning. If you
        desire it to only be user writable, set the 'directory_umask' option
        to '077' or similar. Defaults to '000' unless explicitly set.

PROPERTIES
    See Cache::Cache for default properties.

    (get|set)_cache_root
        See the definition above for the option *cache_root*

    (get|set)_cache_depth
        See the definition above for the option *cache_depth*

    (get|set)_directory_umask
        See the definition above for the option *directory_umask*
