class Module
# Redirect methods to other methods. This simply
# defines methods by the name of a hash key which
# calls the method with the name of the hash's value.
#
# class Example
# redirect_method :hi => :hello, :hey => :hello
# def hello(name)
# puts "Hello, #{name}."
# end
# end
#
# e = Example.new
# e.hello("Bob") #=> "Hello, Bob."
# e.hi("Bob") #=> "Hello, Bob."
# e.hey("Bob") #=> "Hello, Bob."
#
# The above class definition is equivalent to:
#
# class Example
# def hi(*args)
# hello(*args)
# end
# def hey(*args)
# hello(*args)
# end
# def hello
# puts "Hello"
# end
# end
#
def redirect_method( method_hash )
method_hash.each do |targ,adv|
define_method(targ) { |*args| send(adv,*args) }
end
end
end
