getValue

operator fun <T> Column<T>.getValue(o: Entity<ID>, desc: KProperty<*>): T

operator fun <T> CompositeColumn<T>.getValue(o: Entity<ID>, desc: KProperty<*>): T

Reads a property delegated to a CompositeColumn, which stores a single value across several columns:

object Accounts : IntIdTable() {
    val balance = compositeMoney(8, 2, "balance")
}

class Account(id: EntityID<Int>) : IntEntity(id) {
    var balance by Accounts.balance // read and written as one MonetaryAmount

    companion object : IntEntityClass<Account>(Accounts)
}

operator fun <Unwrapped, Wrapped> EntityFieldWithTransform<Unwrapped, Wrapped>.getValue(o: Entity<ID>, desc: KProperty<*>): Wrapped

Reads a property delegated to a transformed column, converting the stored value on the way out:

class Film(id: EntityID<Int>) : IntEntity(id) {
    var tags by Films.tags.transform(wrap = { it.split(",") }, unwrap = { it.joinToString(",") })

    companion object : IntEntityClass<Film>(Films)
}
