Instance Method Details

#get_list(sym_or_string, default = nil) ⇒ Object

Gets the given key as an array. If it’s already an array, it will be returned, otherwise we’ll check if it’s a comma-separated list. The default will be processed in the same way as if was read from the Hash.

def get_list(sym_or_string, default = nil)
  value = get_value(sym_or_string, default)
  return value if(value.is_a?(Array))
  assit(value.is_a?(String) || value.is_a?(Symbol))
  value = value.to_s.split(',').collect do |val|
    val.strip 
  end
end

#get_value(sym_or_string, default = nil) ⇒ Object

Gets the value from the Hash, regardless if it’s stored with a symbol or a key as a string. You may supply a default value - if the default is set to false, the method will raise an argument error. By default, it will return nil if the element isn’t found.

Raises:

  • (ArgumentError)
