SWISH::Prog::Cache - simple in-memory cache class
use SWISH::Prog::Cache; my $cache = SWISH::Prog::Cache->new; $cache->add( foo => 'bar' ); $cache->has( 'foo' ); # returns true $cache->get( 'foo' ); # returns 'bar' $cache->delete( 'foo' ); # removes 'foo' from cache and returns 'bar'
SWISH::Prog::Cache is a simple in-memory caching class. It's basically just a Perl hash, but implemented as a class so that you can subclass it and use different storage (e.g. Cache::* modules).
See SWISH::Prog::Class. Only new or overridden methods are documented here.
Initialize the cache. Called internally by new(). You should not need to call this yourself.
cache([ hash_ref ])
Get/set the internal in-memory cache. The default is just a hash ref. Subclasses are encouraged to implement their own storage.
has( key )
Does key exist in cache.
get( key )
Returns value for key. Returns undef if has( key ) is false.
delete( key )
Delete key from cache.
add( key => value )
Add key to cache with value value.
