Constructor Details

#initialize(config_file) ⇒ ConfParser

Initialize the class with the path to the ‘config_file’ The class objects are dynamically generated by the name of the ‘param’ in the config file. Therefore, if the config file is ‘param = value’ then the itializer will eval “@param = value”

Raises:

  • (Errno::EACCES)

		@config_file = config_file  
end

#get_value(param) ⇒ Object

This method will provide the value held by the object “@param” where “@param” is actually the name of the param in the config file.

# File 'lib/rspider/ConfParser.rb', line 76

def get_value(param)
		self[param]
end

#nil_value(param) ⇒ Object

This method will set the value of ‘@param’ to nil (not in the config file, only in the app).

# File 'lib/rspider/ConfParser.rb', line 90

def nil_value(param)
		self[param]=nil
end

#override_value(param, value) ⇒ Object

This method is simple. Should you need to override a value dynamically, use override_value(param, value) where ‘param’ is the name of the paramater in the config file.
