Class Method Details

.extract_value(operand, tuple) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Extract the value from the operand or tuple

# File 'lib/axiom/function.rb', line 41

def self.extract_value(operand, tuple)
  operand.respond_to?(:call) ? operand.call(tuple) : operand
end

.rename_attributes(operand, aliases) ⇒ Function

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

TODO:

simplify once Attribute#rename works the same as Function#rename

Rename the attribute(s) inside the function
