Rich Buffer Data Structure features
To list a few cool features: You can define your buffer type if necessary. Transparent zero copy is achieved by built-in composite buffer type. A dynamic buffer type is provided out-of-the-box, whose capacity is expanded on demand, just like StringBuffer. There's no need to call flip() anymore. It is often faster than ByteBuffer.
