[Snippet / WIP] Auto<T>: auto supply and verify a value

[Botre]

WIP.

 

Automatically check and updates a value, which is one of the most common tasks of a script.

Can also be used for caching data and verifying its integrity.

 

Example

package org.botre.util;

import java.util.function.Predicate;

import org.botre.functional.FiPr;
import org.osbot.rs07.api.model.NPC;
import org.osbot.rs07.script.Script;
import org.osbot.rs07.script.ScriptManifest;

@ScriptManifest(author = "Botre", info = "", logo = "", name = "AutoExample", version = 0)
public class AutoExample extends Script {

	public Predicate<NPC> VALIDATOR = npc -> npc != null && npc.exists() && npc.getName().equals("Man") && (npc.getInteracting() == null || npc.getInteracting().equals(myPlayer())) && getMap().canReach(npc.getPosition());
	
	private Auto<NPC> target = new Auto<NPC>(() ->  getNpcs().closest(FiPr.adapt(VALIDATOR.and(npc -> !npc.isUnderAttack()))), VALIDATOR);
	
	@Override
	public int onLoop() throws InterruptedException {
		if(!getCombat().isFighting() && target.validate()) {
			target.get().interact("Attack");
		}
		return 500;
	}

}
 

Snippet:

package org.botre.util;

import java.util.Optional;
import java.util.function.Predicate;
import java.util.function.Supplier;

public class Auto<T> {

	private Optional<T> optional;
	private Supplier<T> supplier;
	private Predicate<T> validator;
	
	public Auto(T value, Supplier<T> supplier, Predicate<T> validator) {
		this.optional = Optional.ofNullable(value);
		this.supplier = supplier;
		this.validator = validator;
	}
	
	public Auto(Supplier<T> supplier, Predicate<T> validator) {
		this(null, supplier, validator);
	}
	
	public T get() {
		return optional.get();
	}

	public void supply() {
		optional = Optional.ofNullable(supplier.get());
	}
	
	public boolean validate() {
		if(!optional.isPresent() || !validator.test(optional.get())) supply();
		else return true;
		return optional.isPresent() && validator.test(optional.get());
	}
	
}
