== DESCRIPTION:

'methodfinalizer' is a gem that allows you to declare final class and instance methods in your ruby program.

== FEATURES:

can declare
final class method(s), or
final instance method(s),
implement it and feel safe they will not be redefined

== SYNOPSIS:

Require 'rubygems' and 'methodfinalizer' gems.

require 'rubygems'
require 'methodfinalizer'

class A
# declare your final class and instance methods
final_class_method :method_one
final_instance_methods :method_two, :method_three

def A.method_one
"'method_one' class method in A declared as final"
end

def method_two
"'method_two' instance method in A declared as final"
end

def method_three
"'method_three' instance method in A declared as final"
end
end

Now,

class B < A
# attempting to redeclare 'method_one' as final class method
final_class_method :method_one
end

will yield this error

FinalClassMethodRedeclarationError: cannot declare 'method_one' as final method in child B as parent A declared it already as such

and when,

class B < A
# attempting to redefine 'method_one'
def self.method_one
"'method_one' class method in B"
end
end

will give you

FinalClassMethodRedefinitionError: cannot redefine 'method_one' because it is already defined as final class method in parent A.
