Interface SseEvent

All Known Subinterfaces:
InboundSseEvent, OutboundSseEvent
public interface SseEvent
Base Server Sent Event definition.

This interface provides basic properties of the Server Sent Event, namely ID, Name, and Comment. It also provides access to the Reconnect delay property.

SseEvent is extended by another two interfaces, InboundSseEvent and OutboundSseEvent. The main difference is in how are instances created and how the stored data can be accessed (or provided).

      Get event identifier.

      Contains value of SSE "id" field. This field is optional. Method may return null, if the event identifier is not specified.

      Returns:
      event id.

    • getName

      String getName()
      Get event name.

      Contains value of SSE "event" field. This field is optional. Method may return null, if the event name is not specified.

      Returns:
      event name, or null if not set.

    • getComment

      String getComment()

      Returns:
      comment associated with the event.

    • getReconnectDelay

      long getReconnectDelay()
      Get new connection retry time in milliseconds the event receiver should wait before attempting to reconnect after a connection to the SSE event source is lost.

      Contains value of SSE "retry" field. This field is optional. Method returns RECONNECT_NOT_SET if no value has been set.

      Returns:
      reconnection delay in milliseconds or RECONNECT_NOT_SET if no value has been set.

    • isReconnectDelaySet

      boolean isReconnectDelaySet()
      Check if the connection retry time has been set in the event.
      Returns:
      true if new reconnection delay has been set in the event, false otherwise.
