Hi,

I guess you mean messageReceived and filterWrite?

The NextFilter actually encapsulates both the next and previous filters
in the chain. When you call nextFilter.messageReceived()
messageReceived() will be called on the next filter. While when you call
nextFilter.filterWrite() filterWrite() will be called on the previous
filter.
