Module: FondMemos

Defined in:

lib/fond_memos.rb,
lib/fond_memos/version.rb

Overview

foo = Foo.new foo.bar # expensive foo.bar # fast foo.forget(:bar) foo.bar # expensive again (why did you forget?) foo.bar # fast again (that’s better)

If you memoize a method with arguments, the #hash method will be called on each argument to generate a key to use in FondMemo’s internal hash. To ensure safe and responsible memoizing, it is strongly encouraged to ensure your memoized method arguments have logical hash values.

May you always have fond memos of using this gem!
