Class MessageTrace

java.lang.Object
de.otto.synapse.edison.trace.MessageTrace
@ThreadSafe
public class MessageTrace
extends java.lang.Object
Thread-safe in-memory implementation of a circular MessageStore that is storing all traceEntries in insertion order per channel with a configurable capacity per channel.

Each time an element is added to a full message store, the message store automatically removes its head element.

    • MessageTrace

      public MessageTrace​(int capacityPerChannel)
      Creates a new instance with specified capacity per channel.
      Parameters:
      capacityPerChannel - the size of the underlying ring buffers.

  • Method Details

    • getSenderChannels

      public java.util.SortedSet<java.lang.String> getSenderChannels()

    • getReceiverChannels

      public java.util.SortedSet<java.lang.String> getReceiverChannels()

    • getCapacityPerChannel

      public int getCapacityPerChannel()

    • add

      public void add​(TraceEntry traceEntry)
      Adds a Message to the MessageStore.

      If the capacity of the ring buffer is reached, the oldest message is removed

      Parameters:
      traceEntry - the message to add

    • stream

      public java.util.stream.Stream<TraceEntry> stream()
      Returns a Stream of traceEntries contained in the RegisteredEndpoints.

      The stream will maintain the per-channel insertion order of the traceEntries, but not overall insertion order.

      Returns:
      Stream of traceEntries
