Class ByteBufChecksum

java.lang.Object

io.netty.handler.codec.compression.ByteBufChecksum

All Implemented Interfaces:

java.util.zip.Checksum

Direct Known Subclasses:

ByteBufChecksum.JdkByteBufChecksum, Crc32c

abstract class ByteBufChecksum
extends java.lang.Object
implements java.util.zip.Checksum

Checksum implementation which can directly act on a ByteBuf.

Implementations may optimize access patterns depending on if the ByteBuf is backed by a byte array (ByteBuf.hasArray() is true) or not.
