Overview

SwitchBuilder collects switch cases defined in a decide block. It provides on() and otherwise() methods for defining case branches.

Examples:

decide user[:country] do
  on 'US' do
    simple :us_flow
  end
  on 'UK' do
    simple :uk_flow
  end
  otherwise do
    simple :default_flow
  end
end

def on(value, &block)
  tasks = []
  collector = TaskCollector.new(@parent, tasks)
  collector.instance_eval(&block)
  @cases[value.to_s] = tasks
end

#otherwise { ... } ⇒ Object
