Instance Method Details

#as_json ⇒ Object

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

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

require 'json/add/symbol'
x = :foo.as_json
# => {"json_class"=>"Symbol", "s"=>"foo"}

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

Symbol.json_create(x) # => :foo

require 'json/add/symbol'
