memoizer
Memoizer will memoize the results of your methods. It acts much like
ActiveSupport::Memoizable
without all of that freezing business. The API for
unmemoizing is also a bit more explicit.
Install
$ gem install memoizer
Usage
To memoize an instance method:
class A
include Memoizer
def hello() 'hello!'; end
memoize :hello
end
Or you can memoize many methods at once:
class B
extend Memoizer
def hello() 'hello!'; end
def goodbye() 'goodbye :('; end
memoize :hello, :goodbye
end
Memoizing class methods works the same way:
class C
class << self
include Memoizer
def hello() 'hello!'; end
memoize :hello
end
end
To unmemoize a specific method:
instance = A.new
instance.hello # the hello method is now memoized
instance.unmemoize(:hello) # the hello method is no longer memoized
instance.hello # the hello method is run again and re-memoized
To unmemoize all methods for an instance:
instance = B.new
instance.hello # the hello method is now memoized
instance.goodbye # the goodbye method is now memoized
instance.unmemoize_all # neither hello nor goodbye are memoized anymore
