018/**
019 * Annotation for methods that should be invoked after injection. This occurs last: after constructor injection and
020 * after field injection. It should be placed on a <strong>public method</strong>. Any return value from the method is
021 * ignored. The order of invocation for classes with multiple marked methods (including methods inherited from
022 * super-classes) is not, at this time, defined.
023 *
024 * Tapestry also honors the {@link javax.annotation.PostConstruct} annotation, and treats it identically to
025 * PostInjection. This is both more flexible than PostConstruct (in that methods may have parameters, and multiple methods
026 * may be annotated) but also falls short (Tapestry will only seek out public methods).
