Instance Method Details



  

    #as_json  
  



  

    

Methods as_json and .json_create may be used to serialize and deserialize a OpenStruct object; see Marshal.



Method as_json serializes self, returning a 2-element hash representing self:



require 'json/add/ostruct'
x = OpenStruct.new('name' => 'Rowdy', :age => nil).as_json
# => {"json_class"=>"OpenStruct", "t"=>{:name=>'Rowdy', :age=>nil}}



Method JSON.create deserializes such a hash, returning a OpenStruct object:



OpenStruct.json_create(x)
# => #<OpenStruct name='Rowdy', age=nil>

def as_json(*)
  klass = self.class.name
  klass.to_s.empty? and raise JSON::JSONError, "Only named structs are supported!"
  {
    JSON.create_id => klass,
    't'            => table,
  }
end


  








  

    #to_json(*args)  
  



  

    

Returns a ::JSON string representing self:



require 'json/add/ostruct'
puts OpenStruct.new('name' => 'Rowdy', :age => nil).to_json



Output:



{"json_class":"OpenStruct","t":{'name':'Rowdy',"age":null}}
