# Patch to ActiveResource (based on the 2.3.2 codebase) for including the class name in the JSON generated.
# This is so the receiving end (Rails) can more easily manage the params hash.
#
# The current implementation sends the attributes as top-level JSON keys, which ends up on the other end as:
#  params[:some_attribute]
#  params[:some_other_attribute]
#  params[:something_else] # => not related to the posted JSON
#
# This makes it hard to do things like:
#  obj = SomeModel.new(params[:some_model])

# Comparing JSON parsing (yajl-ruby) and file sizes against YAML (Syck),
# Marshal, and XML (Libxml and Nokogiri) using ruby 1.8.6 (2008-08-11 patchlevel 287) [universal-darwin9.0]
# It should be noted that for this test Yajl, the JSON gem, YAML and Marshal all return Ruby objects (in this case, a Ruby Hash).
# But both the Libxml and Nokogiri tests merely ran a #load call, which returns their respective XMLDocument classes.
# In order to be *fully* accurate I had to convert said document to a hash (in pure ruby) which is
# painfully slow. But made the test more accurate.

# encoding: UTF-8

# This was ported from Yajl (http://github.com/lloyd/yajl)
# The reason for this is because Ruby 1.8's pack/unpack("U"), nor 1.9's native Unicode
# implementation seemed to support surrogate characters (I may be wrong about that...)
# The example below would throw exceptions on *every* attempt I'd tried to decode it.
# But Yajl decodes it fine, so I ported it's decoding logic into pure Ruby for us all
# to enjoy :)
