# Checks if the length of a method exceeds some maximum value.
# Comment lines can optionally be allowed.
# The maximum allowed length is configurable.
#
# You can set constructs you want to fold with `CountAsOne`.
#
# Available are: 'array', 'hash', 'heredoc', and 'method_call'.
# Each construct will be counted as one line regardless of its actual size.
#
# NOTE: The `ExcludedMethods` and `IgnoredMethods` configuration is
# deprecated and only kept for backwards compatibility.
# Please use `AllowedMethods` and `AllowedPatterns` instead.
# By default, there are no methods to allowed.
#
# @example CountAsOne: ['array', 'hash', 'heredoc', 'method_call']
#
# def m
# array = [ # +1
# 1,
# 2
# ]
#
# hash = { # +1
# key: 'value'
