NAME
HTML::Mason::Cache::BaseCache - Base cache object
VERSION
version 1.54
DESCRIPTION
This is the base module for all cache implementations used in Mason. It provides a few
additional methods on top of "Cache::BaseCache" in Dewitt Clinton's "Cache::Cache"
package.
An object of this class is returned from $m->cache.
METHODS
clear ()
Remove all values in the cache.
get (key, [%params])
Returns the value associated with key or undef if it is non-existent or expired. This
is extended with the following optional name/value parameters:
busy_lock => duration
If the value has expired, set its expiration time to the current time plus
duration (instead of removing it from the cache) before returning undef. This is
used to prevent multiple processes from recomputing the same expensive value
simultaneously. The duration may be of any form acceptable to set.
expire_if => sub
If the value exists and has not expired, call sub with the cache object as a
single parameter. If sub returns a true value, expire the value.
get_object (key)
Returns the underlying "Cache::Object" object associated with key. The most useful
methods on this object are
$co->get_created_at(); # when was object stored in cache
$co->get_accessed_at(); # when was object last accessed
$co->get_expires_at(); # when does object expire
expire (key)
Expires the value associated with key, if it exists. Differs from remove only in that
the cache object is left around, e.g. for retrieval by get_object.
remove (key)
Removes the cache object associated with key, if it exists.
set (key, data, [duration])
Associates data with key in the cache. duration indicates the time until the value
should be erased. If duration is unspecified, the value will never expire by time.
$expires_in may be a simple number of seconds, or a string of the form "[number]
[unit]", e.g., "10 minutes". The valid units are s, second, seconds, sec, m, minute,
minutes, min, h, hour, hours, d, day, days, w, week, weeks, M, month, months, y, year,
and years.
