Sample
import br.com.devsrsouza.redissed.RedisObject
class MyObject(database: String, commands: RedissedCommands) : RedisObject(database, commands) {
var hello: String? by string()
var hi: String by string("Hi")
val other: OtherObject by obj { OtherObject(it, commands) }
}
class OtherObject(database: String, commands: RedissedCommands) : RedisObject(database, commands) {
var something = string()
var points: Int = int(0)
}
val database = "my:db"
val commands: RedissedCommands = myClient.redissed
val my = MyObject("$database:obj", commands)
my.hello = "Hello" // setting "Hello" to my:db:obj:hello
my.hi // getting my:db:obj:hi from Redis if not exist return default "Hi"
my.hello = null // removing data from my:db:obj:hello
my.other.something = "Anything" // setting "Anything" to my:db:obj:other:something
my.other.points = 10 // setting 10 to my:db:obj:other:points

Expire
Auto expires a key
var your_key: String? by string().expire(5) // in seconds
You can use withExpire to tell the expiration time for a specific value or get the expiration time of a value
var my_key: Pair<String, Int> by string("my default key").withExpire()
my_key = "my new value expiring in 10 sec" to 10
// get the expiration time of a key
val (value, time) = my_key
// returns the expiration time in seconds or
// returns -2 if the key does not exist.
// returns -1 if the key exists but has no associated expire.
