Module: Garcon::Extensions::MethodReader

Defined in:
lib/garcon/core_ext/method_access.rb

Overview

Note:

That while nil keys will be returned as nil, undefined keys will raise NoMethodErrors. Also note that #respond_to? has been patched to appropriately recognize key methods.

MethodReader allows you to access keys of the hash via method calls. This gives you an OStruct like way to access your hash’s keys. It will recognize keys either as strings or symbols.

Examples:

class StashCache < Hash
  include Garcon::Extensions::MethodReader
end

cash = StashCache.new
cash['box'] = 'full'
cash.box # => 'full'
