Instance Method Details

#as_json ⇒ Object

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

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

require 'json/add/exception'
x = Exception.new('Foo').as_json # => {"json_class"=>"Exception", "m"=>"Foo", "b"=>nil}

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

Exception.json_create(x) # => #<Exception: Foo>

  }
end

#to_json(*args) ⇒ Object

Returns a JSON string representing self:

require 'json/add/exception'

Output:

{"json_class":"Exception","m":"Foo","b":null}
