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.
