Instance Method Details

#memoize(method: nil, function: nil, freeze: false, store_nil: true) ⇒ Object

Memoize either a method or a function. In the former case the memoized results do NOT ONLY depend on the arguments, but ALSO on the object the method is called on. In the latter the memoized results ONLY depend on the arguments given to the function. If the freeze argument is true, the result is frozen if possible to make it immutable. If the store_nil argument is false do not store nil results and always recompute otherwise don’t which is the default.
