Class CBUtil

java.lang.Object

org.apache.cassandra.transport.CBUtil

public abstract class CBUtil
extends java.lang.Object

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