Contents and Example Usage


The org.gfccollective.logging.Loggable trait can be mixed in to add a logger instance to a type that uses slf4j to abstract the underlying logging framework and supports lazy log message computation.

A logger instance with each instance of this trait:

    trait SomeTrait extends AnotherTrait with Loggable {
      def logSomething: Unit = {
        info("This " + "String" + " is " + "constructed" + " lazily")

A logger singleton for all instances of the companion class:

    object SomeThing extends OpenLoggable

    class SomeThing {
      import SomeThing._

      def logSomething: Unit = {
        info("This " + "String" + " is " + "constructed" + " lazily")
