"Hello. Can you guys, please, could send me an example how to add, remove and clear friends from my terrain through API?" Here's my current code:

[muriloowwins]

@OverRide
public void clearFriends(String id) {
Claim claim = me.ryanhamshire.GriefPrevention.GriefPrevention.instance.dataStore.getClaim(Long.parseLong(id));
claim.managers.clear();
me.ryanhamshire.GriefPrevention.GriefPrevention.instance.dataStore.saveClaim(claim);
}

@Override
public void addFriend(String id, UUID friendId) {
    Claim claim = me.ryanhamshire.GriefPrevention.GriefPrevention.instance.dataStore.getClaim(Long.parseLong(id));
    claim.managers.add(friendId.toString());
    me.ryanhamshire.GriefPrevention.GriefPrevention.instance.dataStore.saveClaim(claim);
}

@Override
public void removeFriend(String id, UUID friendId) {
    Claim claim = me.ryanhamshire.GriefPrevention.GriefPrevention.instance.dataStore.getClaim(Long.parseLong(id));
    claim.managers.remove(friendId.toString());
    me.ryanhamshire.GriefPrevention.GriefPrevention.instance.dataStore.saveClaim(claim);
}

Look at how the trust commands are implemented.
