Simple memoize with an expiration time (time-to-live).
MemoizeTtl is not a key based storage. MemoizeTtl is an instance variable storage system backed by a ruby macro that writes getter/generator methods with an expire check pattern for you.
- In process, decentralized cache
- Volatile data debouncing
- Cache with-in cache. Self-expiring memoized values are serializable.
Add this line to your application's Gemfile:
gem 'memoize_ttl'And then execute:
$ bundle
Or install it yourself as:
$ gem install memoize_ttl
This example re-evaluates fish if its called later than 5 seconds apart.
class Taco
extend MemoizeTtl
memoize_ttl :fish, 5 do
puts "eval"
"salmon"
end
end
