In MRI the Hash class is core and written in C. In particular, methods are programmed with explicit C function calls and polymorphism is not honored. For example, []= is crucial in this implementation to maintain the @keys array but hash.c invokes rb_hash_aset() originally.

Superclass of OrderedHash Note that in Rails 2.3, OrderedHash changed from being a subclass of Array to a subclass of Hash . This is contrary to what the documentation says above.

That said, we need to define the basic to_json method in all of them, otherwise they will always use to_json gem implementation, which is backwards incompatible in several cases (for instance, the JSON implementation for Hash does not work) with inheritance and consequently classes as ActiveSupport::OrderedHash cannot be serialized to json.

The simple ActiveSupport::OrderedHash.new [[1,2]] does no longer work in Rails 2.3, so I built a small patch for array that make OrderedHash creation simple again. Code class Array def to_ordered_hash ActiveSupport::OrderedHash[self] end end Usage hash = [[:key, 'value'], [:key2, :value2], [1, 2]].to_ordered_hash hash == {:key=>'value', :key2=>:value2, :1=>2} a more complete but …

This class has dubious semantics and we only have it so that people can write params[:key] instead of params['key'] and they get the same value for both keys.. lazy_load_hooks allows rails to lazily load a lot of components and thus making the app boot faster.

ActiveSupport::OrderedHash is now marked as extractable when using Array#extract_options!. Added Array#prepend as an alias for Array#unshift and Array#append as an alias for Array#<<. The definition of a blank string for Ruby 1.9 has been extended to Unicode whitespace. Also, in Ruby 1.8 the ideographic space U`3000 is considered to be whitespace.
