Lazy Initialization

dev.anvilcraft.lib.v2.util.Lazy<T> is a thread-safe lazy initialization container.

• Construction: new Lazy(Supplier<T>)
• Retrieval: The get() method uses synchronized to ensure initialization happens only once.
• Status: isGotten() checks whether the instance has already been created.
• Typical usage: Caching expensive singleton objects.

Lazy<HeavyObject> lazy = new Lazy<>(HeavyObject::new);
if (!lazy.isGotten()) {
    // Not yet created
}
HeavyObject obj = lazy.get();
