Depends on ProtocolLib.

Versions 1.4.11 and below depended on PacketListenerAPI instead.

API versions 1.4.11 and below are also compatible with APIManager.

Version 1.4.7 is intended for 1.13+ only. For older MC versions, please use 1.4.6.

Usage

import org.bukkit.Bukkit;
import org.bukkit.event.player.PlayerJoinEvent;
import org.inventivetalent.glow.GlowAPI;

public class PlayerJoinListener implements Listener {

    @EventHandler
    public void onPlayerJoin(final PlayerJoinEvent event) {

        //Delay the update by a few ticks until the player is actually on the server
        Bukkit.getScheduler().runTaskLater(this, () -> {

            //Set the event's player glowing in DARK_AQUA for all online players
            GlowAPI.setGlowing(event.getPlayer(), GlowAPI.Color.DARK_AQUA, Bukkit.getOnlinePlayers());
            
        }, 10);

    }

}

import org.bukkit.entity.Entity;
import org.bukkit.entity.Player;
import org.inventivetalent.glow.GlowAPI;

public class MyClass {

    public static void myMethod(Entity entity, Player player) {
        if (GlowAPI.isGlowing(entity, player)) {
            System.out.println("The entity is glowing for the player.");
        }
    }

}

import org.bukkit.entity.Entity;
import org.bukkit.entity.Player;
import org.inventivetalent.glow.GlowAPI;

public class MyClass {

    public static void myMethod(Collection<Entity> entities, Collection<Player> players) {
        CompleteableFuture<Void> future = GlowAPI.setGlowingAsync(entities, GlowAPI.Color.DARK_AQUA, players);

        // Do some other work while that executes in the background

        future.join(); //Wait for glowing to be set
    }

}
