Arrayclass

Arrayclass is a class factory for generating Array based objects whose attributes can be accessed like those of a normal ruby object (or like an array). They are highly memory efficient (almost equivalent to an Array) and fast to work with.

Features

Arrayclass based objects are:

• memory efficient - roughly the same space as a normal array
• quickly instantiated with data

Examples

require 'arrayclass'  

Person = Arrayclass.new(%w(name eye_color watch_brand))
# instantiate with an array
joe = Person.new(%w(Joe brown Casio))

# instantiate an empty object (an array of the expected size is created)
sally = Person.new
sally.name = 'Sally'
sally[0] == 'Sally' # true

Access/modify attributes like a normal object

joe.name # 'Joe'
joe.watch_brand = 'Timex'

Use some array features

joe[1]    # 'brown'
joe[1..2] = ['blue', 'Fossil']
joe.each {|attribute| # do something with attribute }

Arrayclass derived classes can be subclassed

class BigPerson < Person
  def some_new_function
  end

  # push on another attribute
  self.add_member('shoe_type')

  # (haven't written a remove_member function yet...)
end

BigPerson.new

Installation

gem install arrayclass
