Public Instance Methods

as_json(*) click to toggle source

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)
# File json/lib/json/add/complex.rb, line 29

    JSON.create_id =>,
    'r'            => real,
    'i'            => imag,

puts Complex(2).to_json
puts Complex(2.0, 4).to_json
