Public Class Methods

detect(vm, options) click to toggle source

Returns the class of the registered Installer class which matches first (according to it’s priority) or ‘nil` if none matches.

@param vm [Vagrant::VM] @param options [Hash]

# File lib/vagrant-vbguest/installer.rb, line 43
def detect(vm, options)
  @installers.keys.sort.reverse.each do |prio|
    klass = @installers[prio].detect { |k| k.match?(vm) }
    return klass if klass
  end
  return nil
end

  @vm = vm
  @env = vm.env
  @options = options
  @iso_path = nil
end

Register an Installer implementation. All Installer classes which wish to get picked automaticly using their ‘#match?` method have to register. Ad-hoc or small custom Installer meight not need to get registered, but need to get passed as an config option (`installer`)

Registration takes a priority which defines how specific the Installer matches a system. Low level installers, like “linux” or “bsd” use a small priority (2), while distribution installers use higher priority (5). Installers matching a specific version of a distribution should use heigher priority numbers.

@param installer_class [Class] A reference to the Installer class. @param prio [Fixnum] Priority describing how specific the Installer matches. (default: ‘5`)

# File lib/vagrant-vbguest/installer.rb, line 31
def register(installer_class, prio = 5)
  @installers ||= {}
  @installers[prio] ||= []
  @installers[prio] << installer_class
