#retrieve ⇒ Object

Defining a retrieve method seems to stop Puppet looking for an getter method in the provider.

The idea is copied from the Exec type.

def retrieve

  # See comments about how this works by Daniel Pittman in the Exec
  # Puppet source code.

  if @resource.check_all_attributes
    return :notrun
  else
    return self.should
  end
end

#sync ⇒ Object

Defining a sync method seems to stop Puppet looking for an setter method in the provider.
