Configuration options and utility methods for option access. Rack::Cache uses the Rack Environment to store option values. All options documented below are stored in the Rack Environment as "rack-cache.<option>", where <option> is the option name.
The underlying options Hash. During initialization (or outside of a request), this is a default values Hash. During a request, this is the Rack environment Hash. The default values Hash is merged in underneath the Rack environment before each request is processed.
# File lib/rack/cache/options.rb, line 108 def options @env || @default_options end
Set multiple options.
# File lib/rack/cache/options.rb, line 113 def options=(hash={}) hash.each { |key,value| write_option(key, value) } end
Set an option. When option is a Symbol, it is set in the Rack Environment as "rack-cache.option". When option is a String, it exactly as specified. The option argument may also be a Hash in which case each key/value pair is merged into the environment as if the set method were called on each.
# File lib/rack/cache/options.rb, line 122 def set(option, value=self, &block) if block_given? write_option option, block elsif value == self self.options = option.to_hash else write_option option, value end end
