Refs API - DevNatan/inventory-framework GitHub Wiki

Refs API allows you to assign a reference to a component in a context, that is a useful since components are not directly accessible.

• Introduction

Refs API is a very simple API that creates a link to a component. A common use case of Refs API is: I have a component X in my view, specified in onRender and I want to update it on some other handler like onClick, how do I do it? Let's see!

abstract class PlatformView {

    /** Creates a new unassigned reference instance. */
    @ApiStatus.Experimental
    protected final <E> Ref<E> ref();
}

The code above is the method signature of a Ref. Like in State Management, a Ref is create in view class top level. You create a Ref globally and access it through a Context, exactly like states.
