trait Propagation[ReaderMedium, WriterMedium] extends AnyRef

Inter-process Context propagation interface. Implementations are responsible from reading and writing a lossless representation of a given Context instance to the appropriate mediums. Out of the box, Kamon ships with two implementations:

  • HttpPropagation: Uses HTTP headers as the medium to transport the Context data.
  • BinaryPropagation: Uses byte streams as the medium to transport the Context data.

Abstract Value Members

  1. abstract def read(medium: ReaderMedium): Context

    Reads a Context from a ReaderMedium instance.

    Reads a Context from a ReaderMedium instance. If there is any problem while reading the Context then Context.Empty should be returned instead of throwing any exceptions.

  2. abstract def write(context: Context, medium: WriterMedium): Unit

    Attempts to write a Context instance to the WriterMedium.
