public class StompSubframeAggregator
extends io.netty.handler.codec.MessageAggregator<StompSubframe,StompHeadersSubframe,StompContentSubframe,StompFrame>

A ChannelHandler that aggregates an StompHeadersSubframe and its following StompContentSubframes into a single StompFrame. It is useful when you don't want to take care of STOMP frames whose content is 'chunked'. Insert this handler after StompSubframeDecoder in the ChannelPipeline:
