MotionBitmask

This is a simple implementation of generic bitmasks for use in RubyMotion.

This is a work in progress, but is used in production in apps in App Store. YMMV.

Installation

Install with

gem install motion-bitmask

or add to your Gemfile

gem 'motion-bitmask'

Usage

Create a new bitmask with

bitmask = Bitmask.new([:first_value, :second_value, :third_value])

Set a value with

bitmask << :first_value

Check if a given value is set with

bitmask.set?(:first_value)

Get an array of all set values with

bitmask.values => [:first_value]

Get an array of all allowed values with

bitmask.allowed_values => [:first_value, :second_value, :third_value]

Persistence

motion-bitmask does not have an opinion on how values are persisted but support setting the initial bitmask field with

bitmask = Bitmask.new(INITIAL_VALUE, [:first_value, :second_value, :third_value])

To get the current "raw" value of the bitmask, use

bitmask.raw_value = > 1
