Examples of RawDataBuffer

net.timewalker.ffmq3.utils.RawDataBuffer

A RawDataBuffer is a dynamically growing byte array.

It implements {@link java.io.DataOutput} and {@link java.io.DataInput} to write or read data plus additional null-safe versions of the methods.

This class does not implement any synchronization nor bound checking for maximum performance.
Note that the UTF read/write methods are not compatible with the JDK implementation because they were modified to take advantage of the RawDataBuffer layout.
