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).

Since:

2.1
