org.springframework.messaging.simp.stomp.BufferingStompDecoder
An extension of {@link org.springframework.messaging.simp.stomp.StompDecoder}that buffers content remaining in the input ByteBuffer after the parent class has read all (complete) STOMP frames from it. The remaining content represents an incomplete STOMP frame. When called repeatedly with additional data, the decode method returns one or more messages or, if there is not enough data still, continues to buffer.
A single instance of this decoder can be invoked repeatedly to read all messages from a single stream (e.g. WebSocket session) as long as decoding does not fail. If there is an exception, StompDecoder instance should not be used any more as its internal state is not guaranteed to be consistent. It is expected that the underlying session is closed at that point. @author Rossen Stoyanchev @since 4.0.3
