You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: class_condition_handler.rb
    path of file: ./repos/yard/lib/yard/handlers/ruby
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
# Matches if/unless conditions inside classes and attempts to process only
# one branch (by evaluating the condition if possible).
#
# @example A simple class conditional
#   class Foo
#     if 0
#       # This method is ignored
#       def xyz; end
#     end
#   end
class YARD::Handlers::Ruby::ClassConditionHandler < YARD::Handlers::Ruby::Base
  handles meta_type(:condition)
  namespace_only

  proces
    
  def parse_condition
    condition = nil

    # Right now we can handle very simple unary conditions like:
    #   if true
    #   if false
    #   if 0
    #   if 100 (not 0)
    #   if defined? SOME_CONSTANT
    #
    # The last case will do a lookup in the registry and then one
    # in the Ruby world (using eval).
    case statement.condition.type
    when :int
      condition = statement.condition[0] != "0"
    when :defined
      # defined? keyword used, let's see if we can look up the name
      # in the registry, then we'll try using Ruby's powers. eval() is not
      # *too* dangerous here since code is not actually executed.
      arg = statement.condition.first

      if arg.type == :var_ref
        name = arg.source
        obj = YARD::Registry.resolve(namespace, name, true)

          condition = true if obj || (name && Object.instance_eval("defined? #{name}"))
