Class HandlerInvoker

java.lang.Object

tech.guilhermekaua.spigotboot.inventoryapi.internal.HandlerInvoker

@Internal
public final class HandlerInvoker
extends Object

Reflective dispatcher for the protected View lifecycle handlers. Every handler Method is resolved and made accessible once in the static initializer, so the engine phases and the registry share one cached handle per handler instead of resolving it on every dispatch.

Method Details

invoke

public static void invoke(@NotNull
 @NotNull Method handler,
 @NotNull
 @NotNull View view,

Parameters:

handler - the cached handler method, one of the constants of this class

view - the view to dispatch on

arg - the single handler argument (builder or per-phase context)

Throws:

IllegalStateException - when the handler throws a checked exception or the reflective dispatch itself fails
