Package io.netty.handler.codec.compression

Class ByteBufChecksum

java.lang.Object

io.netty.handler.codec.compression.ByteBufChecksum

All Implemented Interfaces:

Checksum

Direct Known Subclasses:

ByteBufChecksum.SlowByteBufChecksum, Crc32c

abstract class ByteBufChecksum
extends Object
implements 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.
