class Exception

See as_json.

# File json/lib/json/add/exception.rb, line 9
def self.json_create(object)
  result = new(object['m'])
  result.set_backtrace object['b']
  result
end

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>

# File json/lib/json/add/exception.rb, line 29
def as_json(*)
  {
    JSON.create_id => self.class.name,
    'm'            => message,
    'b'            => backtrace,
  }
end

Returns a JSON string representing self:

require 'json/add/exception'
puts Exception.new('Foo').to_json

Output:

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