Class Inheritance
Imports
io.netty.buffer.ByteBuf, .ByteBufAllocator, .ByteBufUtil, .CompositeByteBuf, java.nio.charset.StandardCharsets, java.util.Collection
A flyweight class that can be used to encode/decode tagging metadata information to/from ByteBuf. This is intended for low-level efficient manipulation of such buffers. See TaggingMetadata for an Iterator-like approach to decoding entries.
