<?php /** * TODO: Fix shitty doc. * * Provides type assertions for public object properties. All public properties are affected by this library.

This is * the default behavior af all public properties, unless configured otherwise. * - Guarded property: the property can be set by everything, but the value must pass a custom check for type/format, * provided by the object. * * In both cases the checks only apply for external callers (outside the object).
