This is the support site for the book Java NIO by Ron Hitchens, published by O' Reilly & Associates. This site hosts the code examples associated with the book. 7 Java Nio Asynchronous Channels Tutorial . In this book, we provide a series of tutorials on Java NIO examples that will help you kick-start your own projects. learning about NIO, even for those who don't have much Java programming Greg Travis examines NIO in his book, JDK Tutorial (Manning Publications.
Most of the differences between direct and non-direct ByteBuffer derived from the fact that one is inside heap memory while other is outside heap. You can create non-direct byte buffer either by allocating space for buffer's content or by wrapping an existing byte array into a buffer.
Pro Java 7 NIO.2
If a memory mapped file is shared between multiple processes then you need to ensure that it won't get corrupted i. ByteBuffer class.
It returns true if byte buffer is direct. These were some differences between direct, non-direct and mapped byte buffers in Java. Since ByteBuffer indexes are integer based , which effectively limits their addressable space up to 2GB, you may want to check BigByteBuffer class from Java 1. That's all on the difference between direct, non-direct and mapped byte buffer in Java.
Just remember that Direct buffers are allocated outside heap and they are not in control of Garbage Collection while non-direct buffers are simply a wrapper around byte arrays, located inside heap.
Memory mapped files can be accessed by using MappedByteBuffer, which is also a direct buffer. Emails from random people that's you often get flagged as spam and I don't see them.
Also, I've occasionally not been able to reply to a question because the sender's corporate mail system won't let my response through. Gotta Problem? If you need help with an NIO problem, or anything within my expertise , I can provide consulting services worldwide.
Please directly and I'll make the pain go away. Update: I'm now employed full-time, so my availabilty for consulting projects is limited. But I still may be able to help. I haven't been doing much speaking on the subject of NIO lately.
If you'd like me to give a talk about NIO, contact me. I gave two NIO talks this time around. Some improvements have been made to the design with an eye to better leveraging the concurrency APIs and improving worker thread management. Final slides for both presentations as well as the code for the server prototype are available here.
There is also information there about accessing the Subversion repository for all the code. The slides can be found here. I updated the code used in the slides to make use of 1.
The codebase upon which the samples are based is 1. It is, however, well-tested and production quality. The example code in the slides has been updated to the more modern 1. But it can still be informative as an example to get you started.
I haven't had a chance to neatly package the code for distribution yet. But it is available under an Apache 2. You will need a copy of the Subversion client svn.
If you're interested in helping complete the port to 1. The slides are available on the JavaOne web site. Unfortunately, I was not able to get a working, bundled example app completed in time for JavaOne.
I intend to finish up and make the improved code available soon - as open source. If you want to know when the code is ready, or maybe help out with it, drop me a line at the email address below.
It was about making use of XQuery from Java. There was nothing about NIO in this talk, but we won a Top award, so it must have been pretty good.
The presentation can be found online here. If you plan to attend, please let me know or contact me at the conference, I'd love to hear from European readers.

Memory mapped files can be accessed by using MappedByteBuffer, which is also a direct buffer. Should one need to read from a different position within the underlying array, whilst not adjusting the writing position, the mark and reset methods have been supplied. If you try to apply a regex to a partially-read line, you have to worry about what to do if the pattern you're looking for is split between one read and another - and this is probably more trouble than you want to deal with, unless you have specific needs which require it.
