3.6.3 Further Details

Though the preceding sub-section provides enough information to allow the reader
to implement a basic non-blocking server, there are other methods that are often
required in more sophisticated implementations. Not all of the remaining methods
associated with Java's NIO will be covered in this section, but the reader should fi nd
that those that are covered are the only additional ones that are needed for many
