Module: Mize::Reload

Defined in:
lib/mize/reload.rb

Overview

Reload/invalidation hook, prepended into any module that memoizes an instance method.

When a class defines (or inherits) its own reload, Mize wraps it so the cache is guaranteed to be cleared alongside whatever the user's reload does, keeping memoized state consistent after a full object reload.

Instance Method Details

#reload ⇒ Object

Run the parent reload (if any), then clear Mize's bookkeeping and the object's memoization cache.

The whole sequence is serialized on Mize.synchronize. Mize.wrapped is reset so a re-memoization with different options is allowed, and mize_cache_clear drops every cached value for this object.

Returns:

  • (Object) —

    The result of the parent reload if one was defined, otherwise self.
