Instance Method Details

#asc ⇒ Relation::Operation::Order::Ascending

Sort the attribute in ascending order

Examples:

ascending = attribute.asc

Returns:



26
27
28
 
# File 'lib/axiom/attribute/comparable.rb', line 26

def asc
  Relation::Operation::Order::Ascending.new(self)
end

#desc ⇒ Relation::Operation::Order::Descending

Sort the attribute in descending order

Examples:

descending = attribute.desc

Returns:



38
39
40
 
# File 'lib/axiom/attribute/comparable.rb', line 38

def desc
  Relation::Operation::Order::Descending.new(self)
end
