EntityEquality

trait EntityEquality extends AnyRef

Entity identifier provider for equality (especially for scalikejdbc.RelationalSQL operation).

Notice: Inheritance is not supported.

Source
EntityEquality.scala
Example: 

  1. class Person(val id: Long) extends EntityEquality { override val entityIdentity = id }
class Member(override val id: Long) extends Person(id)

val p1 = new Person(123)
val p2 = new Person(123)
val m1 = new Member(123)
val m2 = new Member(123)

p1 == p2 && p2 == p1 // true
p1 == m1 || m1 == p1 // false
m1 == m2 && m2 == m1 // true

Abstract Value Members

  1. abstract def entityIdentity: Any

    Identity for this entity.
