def configuration_class
  ConfigurationMethods.find_configuration_class(self)
end

#def_configuration(&blk) ⇒ Object

Helper method to define class specific configuration class.

def_configuration(&blk) is available when you include this module

# Example: class Base

include Fuguta::Configuration::ConfigurationMethods
def_configuration do
  param :xxxx
  param :yyyy
end

end

Above example does exactly same thing as below:

class Base

class Configuration < Fuguta::Configuration
  param :xxxx
  param :yyyy
end
@configuration_class = Configuration

end

# Examples for new classes of Base inheritance. class A < Base

def_configuration do
  param :zzzz
end
def_configuration do
  param :xyxy
end

p Configuration # => A::Configuration
p Configuration.superclass # => Base::Configuration
p @configuration_class # => A::Configuration

end

class B < A

p self.configuration_class # => A::Configuration

end
