trait LogSource[-T] extends AnyRef

This trait defines the interface to be provided by a “log source formatting rule” as used by akka.event.Logging’s apply/create method.

See the companion object for default implementations.

Example:

trait MyType { // as an example
  def name: String
}

implicit val myLogSourceType: LogSource[MyType] = new LogSource[MyType] {
  def genString(a: MyType) = a.name
}

class MyClass extends MyType {
  val log = Logging(eventStream, this) // will use "hallo" as logSource
  def name = "hallo"
}

The second variant is used for including the actor system’s address:

trait MyType { // as an example
  def name: String
}

implicit val myLogSourceType: LogSource[MyType] = new LogSource[MyType] {
  def genString(a: MyType) = a.name
  def genString(a: MyType, s: ActorSystem) = a.name + "," + s
}

class MyClass extends MyType {
  val sys = ActorSystem("sys")
  val log = Logging(sys, this) // will use "hallo,akka://sys" as logSource
  def name = "hallo"
}

The default implementation of the second variant will just call the first.

    (Since version 2.12.16) Use formatString.format(value) instead of value.formatted(formatString), or use the f"" string interpolator. In Java 15 and later, formatted resolves to the new method in String which has reversed parameters.
