class Range

See as_json.

# File json/lib/json/add/range.rb, line 9
def self.json_create(object)
  new(*object['a'])
end

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

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

require 'json/add/range'
x = (1..4).as_json     # => {"json_class"=>"Range", "a"=>[1, 4, false]}
y = (1...4).as_json    # => {"json_class"=>"Range", "a"=>[1, 4, true]}
z = ('a'..'d').as_json # => {"json_class"=>"Range", "a"=>["a", "d", false]}

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

Range.json_create(x) # => 1..4
Range.json_create(y) # => 1...4
Range.json_create(z) # => "a".."d"

# File json/lib/json/add/range.rb, line 31
def as_json(*)
  {
    JSON.create_id  => self.class.name,
    'a'             => [ first, last, exclude_end? ]
  }
end

Returns a JSON string representing self:

require 'json/add/range'
puts (1..4).to_json
puts (1...4).to_json
puts ('a'..'d').to_json

Output:

{"json_class":"Range","a":[1,4,false]}
{"json_class":"Range","a":[1,4,true]}
{"json_class":"Range","a":["a","d",false]}
