AliasMethod

Macros

alias_method(new_method, old_method)

Defines new_method as an alias of old_method.

This creates a new method new_method that invokes old_method.

Note that due to current language limitations this is only useful when neither named arguments nor blocks are involved.

class Person	
  getter name	
	
  def initialize(@name)	
  end	
	
  alias_method full_name, name	
end	
	
person = Person.new "John"	
person.name #=> "John"	
person.full_name #=> "John"
