CLASS net/minecraft/class_9139 net/minecraft/network/codec/PacketCodec
	COMMENT A codec that is used for serializing a packet.
	COMMENT
	COMMENT <p>Packet codecs serialize to, and deserialize from, {@link net.minecraft.network.PacketByteBuf},
	COMMENT which is a stream of data. To integrate the classic {@link net.minecraft.network.PacketByteBuf}-based
	COMMENT code, use {@link #of(ValueFirstEncoder, PacketDecoder)}
	COMMENT like this:
	COMMENT
	COMMENT <pre>{@code
	COMMENT public static final PacketCodec<PacketByteBuf, MyPacket> CODEC = PacketCodec.of(MyPacket::write, MyPacket::new);
	COMMENT
	COMMENT private MyPacket(PacketByteBuf buf) {
	COMMENT \tthis.text = buf.readString();
	COMMENT }
	COMMENT
	COMMENT private void write(PacketByteBuf buf) {
	COMMENT \tbuf.writeString(this.text);
	COMMENT }
	COMMENT }</pre>
	COMMENT
	COMMENT <p>While this serves similar functions as codecs in the DataFixerUpper library,
	COMMENT the two are wholly separate and DataFixerUpper methods cannot be used with this.
	COMMENT However, a packet codec may reference a regular codec by using {@link
	COMMENT PacketCodecs#codec}, which serializes the data to NBT.
	COMMENT
	COMMENT <p>See {@link PacketCodecs} for codecs to serialize various objects.
	COMMENT
	COMMENT @param <B> the type of the buffer; {@link net.minecraft.network.RegistryByteBuf}
	COMMENT for play-phase packets, {@link net.minecraft.network.PacketByteBuf} for other
	COMMENT phases (like configuration)
	COMMENT @param <V> the type of the value to be encoded/decoded

		COMMENT
		COMMENT @apiNote For example, {@link net.minecraft.util.math.BlockPos#PACKET_CODEC}
		COMMENT is defined as {@code PacketCodec<ByteBuf, BlockPos>}. To use this codec
		COMMENT where {@link net.minecraft.network.PacketByteBuf} is expected, you can call
		COMMENT this method for easy casting, like: {@code PACKET_CODEC.cast()}.
		COMMENT Doing this is generally safe and will not result in exceptions.

		COMMENT <p>This does not encode anything. Instead, it throws {@link

		COMMENT <p>This can be used to transform a codec for a simple value (like a string)

		COMMENT <p>For example, passing {@code PacketCodecs::optional} makes the value
		COMMENT optional. Additionally, this method can be used like Stream {@link
