MethodCache
MethodCache lets you easily cache the results of any instance method or class method in Ruby.
Usage:
class Foo
extend MethodCache
cache_method :bar
def
# do expensive calculation
end
cache_class_method :baz, :clone => true, :expiry => 1.day
def self.baz
# do some expensive calculation that will be invalid tomorrow
end
end
foo = Foo.new
foo. # does calculation
foo. # cached
Foo.baz # does calculation
Foo.baz # cached
Foo.invalidate_cached_method(:baz)
Foo.baz # does calculation
Foo.baz # cached
Install:
gem install method_cache
