Class UnsafeDirectLittleEndian

java.lang.Object

io.netty.buffer.ByteBuf

io.netty.buffer.WrappedByteBuf

io.netty.buffer.UnsafeDirectLittleEndian

All Implemented Interfaces:

io.netty.buffer.ByteBufConvertible, io.netty.util.ReferenceCounted, Comparable<io.netty.buffer.ByteBuf>

public class UnsafeDirectLittleEndian
extends io.netty.buffer.WrappedByteBuf

The underlying class we use for little-endian access to memory. Is used underneath ArrowBufs to abstract away the Netty classes and underlying Netty memory management.
