Module: Gibbler::Array

Includes:
Object
Included in:
Array
Defined in:
lib/gibbler.rb

Overview

Creates a digest based on:

  • parse each element into an Array of digests like: CLASS:INDEX:VALUE.__gibbler

    • The gibbler method is called on each element so if it is a Hash or Array etc it will be parsed recursively according to the gibbler method for that class type.

  • Digest the Array of digests

  • Return the digest for class:length:value where:

    • “class” is equal to the current object class (e.g. Array).

    • “length” is the size of the Array of digests (which should equal the number of elements in the original Array object).

    • “value” is the Array of digests joined with a colon (“:”).

This method can be used by any class with an each method.

class MyNamedArray 
  include Gibbler::Array
