Options

If true, will use symbols instead of strings for the keys. |
# File lib/multi_json.rb, line 64 def decode(string, options = {}) engine.decode(string, options) rescue engine::ParseError => exception raise DecodeError, exception.message, exception.backtrace end
The default engine based on what you currently have loaded and installed. First checks to see if any engines are already loaded, then checks to see which are installed if none are loaded.
# File lib/multi_json.rb, line 24 def default_engine return :yajl if defined?(::Yajl) return :json_gem if defined?(::JSON) REQUIREMENT_MAP.each do |(library, engine)| begin require library return engine rescue LoadError next end end :ok_json end
Encodes a Ruby object as JSON.
# File lib/multi_json.rb, line 71 def encode(object) engine.encode(object) end
Get the current engine class.
# File lib/multi_json.rb, line 8 def engine return @engine if @engine self.engine = self.default_engine @engine end
Set the JSON parser utilizing a symbol, string, or class. Supported by default are:
:json_gem
:json_pure
:ok_json
:yajl
# File lib/multi_json.rb, line 47 def engine=(new_engine) case new_engine when String, Symbol require "multi_json/engines/#{new_engine}" @engine = MultiJson::Engines.const_get("#{new_engine.to_s.split('_').map{|s| s.capitalize}.join('')}") when Class @engine = new_engine else raise "Did not recognize your engine specification. Please specify either a symbol or a class." end end
