Module: Plushie::UI::MemoCache Private

Defined in:

lib/plushie/ui.rb

Overview

This module is part of a private API. You should avoid using this module if possible, as it may be removed or be changed in the future.

Thread-local memo cache used during tree normalization. The runtime seeds the previous cache before normalize and captures the new cache after.

Class Method Summary

• .capture ⇒ Object private

  Capture and clear the current cache (called by runtime after normalize).

• .current ⇒ Hash private

  The current render's memo cache (being built).

• .prev ⇒ Hash private

  The previous render's memo cache.

• .seed(cache) ⇒ Object private

  Set the previous cache (called by runtime before normalize).

• .store(key, value) ⇒ Object private

  Store a memo result in the current cache.
