Instance Method Details

#as_json ⇒ Object

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

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

require 'json/add/complex'
x = Complex(2).as_json      # => {"json_class"=>"Complex", "r"=>2, "i"=>0}
y = Complex(2.0, 4).as_json # => {"json_class"=>"Complex", "r"=>2.0, "i"=>4}

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

Complex.json_create(x) # => (2+0i)
Complex.json_create(y) # => (2.0+4i)

  {
    JSON.create_id => self.class.name,
    'r'            => real,
    'i'            => imag,
  }
end

#to_json(*args) ⇒ Object

Returns a JSON string representing self:

require 'json/add/complex'
puts Complex(2).to_json
puts Complex(2.0, 4).to_json

Output:

{"json_class":"Complex","r":2,"i":0}
{"json_class":"Complex","r":2.0,"i":4}
