Actually just
public Transformer getDecoder()
public Transformer getEncoder()
If you look at org.glassfish.grizzly.FilterChainTest you see both API's being used at the same time.
But I think if you only use the methods
WriteResult result = (WriteResult) filterChain.write(connection,message).get();
ReadResult readResult =(ReadResult) filterChain.read(connection).get();
a class like UTFStringFilter is bigger then it would need to be
UTFStringFilter execute or postExecute
will never be called (Maybe in async mode they will and I am overlooking a usage)
The call graph is aso different opposed to setting up a server.
So I would just like to check if any simplyfications could be possible?
