Padrino.cache.clear

# File lib/padrino-cache.rb, line 19
def cache

end

Set the caching engine.

@param value

Instance of Moneta store

@example

Padrino.cache = Padrino::Cache.new(:LRUHash) # default choice
Padrino.cache = Padrino::Cache.new(:File, :dir => Padrino.root('tmp', app_name.to_s, 'cache')) # Keeps cached values in file
Padrino.cache = Padrino::Cache.new(:Memcached) # Uses default server at localhost
Padrino.cache = Padrino::Cache.new(:Memcached, :server => '127.0.0.1:11211', :exception_retry_limit => 1)
Padrino.cache = Padrino::Cache.new(:Memcached, :backend => memcached_or_dalli_instance)
Padrino.cache = Padrino::Cache.new(:Redis) # Uses default server at localhost
Padrino.cache = Padrino::Cache.new(:Redis, :host => '127.0.0.1', :port => 6379, :db => 0)
Padrino.cache = Padrino::Cache.new(:Redis, :backend => redis_instance)
Padrino.cache = Padrino::Cache.new(:Mongo) # Uses default server at localhost
Padrino.cache = Padrino::Cache.new(:Mongo, :backend => mongo_client_instance)

# You can manage your cache from anywhere in your app:

Padrino.cache['val'] = 'test'
Padrino.cache['val'] # => 'test'
Padrino.cache.delete('val')
Padrino.cache.clear
