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 with a configurable capacity.

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

Constructor Detail

MessageTrace

public MessageTrace(int capacity,
                    java.lang.Iterable<de.otto.synapse.endpoint.MessageEndpoint> endpoints)

Creates a new instance with specified capacity.

Parameters:

capacity - the size of the underlying ring buffer.

Method Detail

getSenderChannels

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

getReceiverChannels

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

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 insertion order of the traceEntries.

Returns:

Stream of traceEntries
