Public Instance methods

configuration()

configure adds the options method to a class which allows it to access the global configuration hash.

name
an arrays of symbols representing the attributes on the object.

# File lib/utility/configuration.rb, line 51
  def configuration()
    class_eval "def options\nConfiguration.instance.options\nend\n"
  end
logger(loglevel='DEBUG', logto=['stderr','server'])

logger defines a named log and log method for the class

loglevel
the level of logging to do

# File lib/utility/log.rb, line 53
  def logger(loglevel='DEBUG', logto=['stderr','server'])
    class_eval "@log = Log.instance.loginit(self.name, \"\#{loglevel}\", \#{logto.inspect})\ndef log\nself.class.instance_variable_get :@log\nend\n"
  end
property(*sym)

Properties modifies class Module by adding the property method which:

  1. creates read/write accessors for each symbol.
  2. defines the to_yaml_properties for use by the database for all symbols.
  3. defines the :id attribute
sym
an arrays of symbols representing the attributes on the object.

    if Configuration.instance.options['props_are_accessors_only']
      attr_accessor(*sym)

      return
    end
    sym.each do |s|
