class Phony::LocalSplitters::Fixed

Local splitter class to split the last part of a number, i.e. minus cc or ndc.

Countries can create new instances according to their needs.

Note: Countries should use instance_for

to avoid getting new local splitter instances.

Public Class Methods

instance_for(format = nil) click to toggle source

Get a splitter for the given format.

Caches the created splitter for the given format.

# File lib/phony/local_splitters/fixed.rb, line 21
def self.instance_for format = nil
  @mapping[format] ||= new(format)
end
new(format = nil) click to toggle source

Initialize with a local format, like [3, 2, 2] (also the default).

The format [3, 2, 2] splits a number like ‘3332222’ into [‘333’, ‘22’, ‘22’].

# File lib/phony/local_splitters/fixed.rb, line 29
def initialize format = nil
  format = format && format.dup || [3, 2, 2]
  @format, @length = extract_params format
  @format << @format.pop + 10
end

  if format.last.respond_to? :max
    last = format.pop

    length = (length+last.min..length+last.max)
    format << last.min
  else
    length = format.inject(0) { |total, part| total + part }
  end
  [format, length]

Split a local number according to an assumed country specific format.

Examples

  • split ‘3643533’ # => [‘364’, ‘35’, ‘33’] # (Switzerland)

# File lib/phony/local_splitters/fixed.rb, line 54
def split number
  @format.inject([]) do |result, size|
    result << number.slice!(0..size-1)
    return result if number.empty?
    result
  end
