Module: Hashie::Extensions::MethodWriter

Defined in:
lib/hashie/extensions/method_access.rb

Overview

MethodWriter gives you #key_name= shortcuts for writing to your hash. Keys are written as strings, override #convert_key if you would like to have symbols or something else.

Note that MethodWriter also overrides #respond_to such that any #method_name= will respond appropriately as true.

Examples:

class MyHash < Hash
  include Hashie::Extensions::MethodWriter
end

h = MyHash.new
h.awesome = 'sauce'
h['awesome'] # => 'sauce'
