Class CBUtil

java.lang.Object

org.apache.cassandra.transport.CBUtil

public abstract class CBUtil
extends java.lang.Object

ChannelBuffer utility methods. Note that contrarily to ByteBufferUtil, these method do "read" the ChannelBuffer advancing it's (read) position. They also write by advancing the write position. Functions are also provided to create ChannelBuffer while avoiding copies.
