module Oj
# A SAX style parse handler for JSON hence the acronym SAJ for Simple API
# for JSON. The Oj::Saj handler class can be subclassed and then used with
# the Oj::Saj key_parse() method or with the more resent
# Oj::Parser.new(:saj). The Saj methods will then be called as the file is
# parsed.
#
# With Oj::Parser.new(:saj) each method can also include a line and column
# argument so hash_start(key) could also be hash_start(key, line,
# column). The error() method is no used with Oj::Parser.new(:saj) so it
# will never be called.
#
# @example
#
# require 'oj'
#
# class MySaj < ::Oj::Saj
# def initialize()
# @hash_cnt = 0
# end
#
# def hash_start(key)
# @hash_cnt += 1
# end
# end
#
# cnt = MySaj.new()
# File.open('any.json', 'r') do |f|
# Oj.saj_parse(cnt, f)
# end
#
# or
#
# p = Oj::Parser.new(:saj)
# p.handler = MySaj.new()
# File.open('any.json', 'r') do |f|
# p.parse(f.read)
# 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(key); end
# def hash_end(key); end
# def array_start(key); end
# def array_end(key); end
# def add_value(value, key); end
# def error(message, line, column); end
#

# Create a new instance of the Saj handler class.
