# Scala Common Lib

This project aims to provide a generic common backend interface/impl for java/scala developers.

I32IdGenerator

	val idGen = I32IdGenerator("project_a","user_id", ssdb)

	val id = idGen.getNextId()

List

    val listUserFriends = SsdbList[Int]("user_a", ssdb)

    listUserFriends.multiPushFront(Array(1,2,3,4))

    val listUserMessages = SsdbList[String]("id")

    val listTransaction = SsdbList[Transaction]("user_id")

KeyValueDB

	val kvs = SsdbKVS[String,String]("user_db",ssdb)

        kvs.add("user_id","{ json_user_value }")

	val value = kvs.get("user_id")

	val dbUserProfile = SsdbKVS[Long,UserProfile]("user_profile")

	val jackProfile = UserProfile(123,"Jack",19,"[email protected]")

	dbUserProfile.add(123L, jackProfile)

	val profile = dbUserProfile.get(123)

SortedSet

        val leaderboard = SSdbSortedSet("game_a",ssdb)

        leaderboard.add("user_1",100)

        val rank = leaderboard.rank("user_1")

        val top10 = leaderboard.range(0,10)

JDBC Client

        val client = NativeJdbcClient("jdbc:mysql://127.0.0.1:9000", "user", "password")

        // Insert a row

        client.executeUpdate(

              s"insert into users(id, name, age, created_date) values(?, ?, ?, ?);",

              1, "user1", 1, new Date(1589446762000L))

              

        // Delete a row          

        val afftedRows = client.executeUpdate(s"delete from users where id = ?", 1)
