    • byPayload

      public static <T> Predicate<Event> byPayload(Class<T> payloadType, Predicate<? super T> payloadPredicate)
      Create a Predicate for events whose payload types match the supplied payloadType and whose payloads match the supplied payloadPredicate.
      Parameters:
      payloadType - the required payload type

      type - the type to match against
      Returns:
      the resulting Predicate

    • getType

      public EventType getType()
      Get the type of this Event.
      Returns:
      the event type; never null

    • getTestDescriptor

      public TestDescriptor getTestDescriptor()
      Get the TestDescriptor associated with this Event.
      Returns:
      the TestDescriptor; never null

    • getTimestamp

      public <T> Optional<T> getPayload(Class<T> payloadType)
      Get the payload of the expected type, if available.

      This is a convenience method that automatically casts the payload to the expected type. If the payload is not present or is not of the expected type, this method will return Optional.empty().

      Parameters:
      payloadType - the expected payload type; never null
      Returns:
      an Optional containing the payload; never null but potentially empty
      See Also:

    • getRequiredPayload

      public <T> T getRequiredPayload(Class<T> payloadType) throws IllegalArgumentException
      Get the payload of the required type.

      This is a convenience method that automatically casts the payload to the required type. If the payload is not present or is not of the expected type, this method will throw an IllegalArgumentException.

      Parameters:
      payloadType - the required payload type; never null
      Returns:
      the payload
      Throws:
      IllegalArgumentException - if the payload is of a different type or is not present
