Reference — Enums

All enums are from R4J (no.stelar7.api.r4j.*), mapped without duplicate DTOs.

TierDivisionType — 41 values

TierDivisionType (no.stelar7.api.r4j.basic.constants.types.lol.TierDivisionType) — tier + division.

41 total = 7 tier*4 + 4 solo + UNRANKED. Scale getMmr (TierDivisionUtils.java:78): IRON_IV=0, +100 per division/tier, MASTER=10000, GM=20000, CHALL=30000 + lp. getMmrRange(TierType) (:119): IRON 0..400, ..., CHALLENGER 30000..∞. getTierFromMmr (:136) inverts, getAverageRank (:49) averages ordinals.

TierType — 11 values

TierType (no.stelar7.api.r4j.basic.constants.types.lol.TierType):

UNRANKED, IRON, BRONZE, SILVER, GOLD, PLATINUM, EMERALD, DIAMOND, MASTER, GRANDMASTER, CHALLENGER

11 total. Used for LolApiParameters.rank (:37), Filter.rank (Filter.java:125), leaderboard rank query, Record not applicable. Ordering rank.ordinal() reflects progression.

LaneType — 8 values, 5 playables

LaneType (no.stelar7.api.r4j.basic.constants.types.lol.LaneType):

LaneTypeUtils.playables() (src/main/java/com/safjnest/lol/utils/LaneTypeUtils.java:14): List.of(TOP, JUNGLE, MID, BOT, UTILITY) — 5 values. playableOrder(role) (:22) defines order TOP=0, JUNGLE=1, MID=2, BOT=3, UTILITY=4.

Validation LolApiParameters.role (:168): rejects if not in playables, message must be one of: TOP, JUNGLE, MID, BOT, UTILITY. validateRole(queue, role) (:177): rejects if role!=null && !GameQueueTypeUtils.hasLane(queue).

LeagueShard — 14 active (+ UNKNOWN)

LeagueShard (no.stelar7.api.r4j.basic.constants.api.regions.LeagueShard):

Active list LeagueShardUtils.getActives() (:64): EUW1, NA1, KR, EUN1, JP1, BR1, LA1, LA2, TR1, RU, OC1, VN2, SG2, TW2, ME1 — 15 shards (task says 14 but lists 15 — EUW1 included).

getAccountRegion (:45) maps VN2, OC1, SG2, PH2, TH2, TW2 → ASIA, otherwise shard.toRegionShard(). cacheRegion (:52) = shard.toRegionShard().name() — first segment of Redis los:%s:%s:....

GameQueueType — leaderboard queues

GameQueueType (no.stelar7.api.r4j.basic.constants.types.lol.GameQueueType) — 40+ values, but only 2 for leaderboard:

LEADERBOARD_QUEUES (MongoDB.java:120): List.of(RANKED_SOLO_5X5, RANKED_FLEX_SR).

Canonical mapping

GameQueueTypeUtils (src/main/java/com/safjnest/lol/utils/GameQueueTypeUtils.java):

public static GameQueueType canonicalQueue(GameQueueType queue) {
    return queue == TEAM_BUILDER_RANKED_SOLO ? RANKED_SOLO_5X5 : queue; // :38
}
public static boolean hasLane(GameQueueType queue) { return queue != null && laneQueues.contains(queue); } // :30
public static boolean isCherry(GameQueueType queue) { return queue == GameQueueType.CHERRY; } // :19
public static boolean isRankedSolo(GameQueueType queue) { return canonicalQueue(queue) == RANKED_SOLO_5X5; } // :48
public static GameQueueType defaultQueue() { return RANKED_SOLO_5X5; } // :44

• TEAM_BUILDER_RANKED_SOLO → RANKED_SOLO_5X5 always before persistence/query/validation.
• ALL (string "ALL" case-insensitive) → null in optionalQueue (LolApiParameters.java:57).
• rankHistoryQueue (:61) accepts only RANKED_SOLO_5X5/RANKED_FLEX_SR (canonical).
