fun <T> Column<T>.lookup(): T

Returns the value assigned to this column mapping.

Link copied to clipboard
fun <T, R : Any> Column<T>.lookupInReadValues(found: (T?) -> R?, notFound: () -> R?): R?

Checks if this column has been assigned a value retrieved from the database, then calls the found block with this value as its argument, and returns its result.

open fun refresh(flush: Boolean = false)

Updates the fields of this Entity instance with values retrieved from the database. Override this function to refresh some additional state, if any.
