module Oj
# A Simple Callback Parser (SCP) for JSON. The Oj::ScHandler class should be
# subclassed and then used with the Oj.sc_parse() method. The Scp methods will
# then be called as the file is parsed. The handler does not have to be a
# subclass of the ScHandler class as long as it responds to the desired
# methods.
#
# @example
#
# require 'oj'
#
# class MyHandler < ::Oj::ScHandler
# def initialize()
# @hash_cnt = 0
# end
#
# def hash_start()
# @hash_cnt += 1
# end
# end
#
# cnt = MyHandler.new()
# File.open('any.json', 'r') do |f|
# Oj.sc_parse(cnt, f)
# end
#
# To make the desired methods active while parsing the desired method should
# be made public in the subclasses. If the methods remain private they will
# not be called during parsing.
#
# def hash_start(); end
# def hash_end(); end
# def array_start(); end
# def array_end(); end
# def add_value(value); end
# def error(message, line, column); end
#
class ScHandler
# Create a new instance of the ScHandler class.
def initialize()

# To make the desired methods active while parsing the desired method should

# not be called during parsing.
