ExtendableAccessor

A typesafe convenience class for associating additional data with {@link Extendable} classes. <p> An instance of <code>ExtendableAccessor</code> uses itself as the key in the {@link Extendable#attachments()} so it's best instantiated as a static member. <pre><code> class Foo extends BaseHandler { private static ExtendableAccessor<Link, Bar> LINK_BAR = new ExtendableAccessor<>(Bar.class); void onLinkRemoteOpen(Event e) { Bar bar = LINK_BAR.get(e.getLink()); if (bar is null) { bar = new Bar(); LINK_BAR.set(e.getLink(), bar); } } } </code></pre>

@param <E> An {@link Extendable} type where the data is to be stored @param <T> The type of the data to be stored

class ExtendableAccessor : Extendable (

) {

this();

T get(E e, string key);

void set(E e, T value, string key);

Record attachments();
