Class Packet

java.lang.Object

de.dytanic.cloudnet.driver.network.protocol.Packet

All Implemented Interfaces:

IPacket

Direct Known Subclasses:

PacketClientAuthorization, PacketClientServerChannelMessage, PacketClientServerServiceInfoPublisher, PacketServerSetGlobalLogLevel, PacketServerUpdatePermissions

public class Packet
extends java.lang.Object
implements IPacket

The default simple implementation of the IPacket interface. You can create with the constructor all new packets or use the class as superclass from an another for specific constructor usage.

All packets require a channel, header and a body.

The channel id is the id from that the listeners should be filter The header has the specify information or the data that is important The body has binary packet information like for files, or zip compressed data

Method Detail

getChannel

public int getChannel()

Description copied from interface: IPacket

Returns the channel id, in that the IPacketListenerRegistry class should the listeners work with that packet

Specified by:

getChannel in interface IPacket

Returns:

the channel id in that the packet is defined

getUniqueId

public java.util.UUID getUniqueId()

Description copied from interface: IPacket

Returns the uuid of the packet. Each packet should has a own defined UUID instance, less the callback packets for synchronized messages between client and server

Specified by:

getUniqueId in interface IPacket

Returns:

the own uniqueId

getHeader

public de.dytanic.cloudnet.common.document.gson.JsonDocument getHeader()

Description copied from interface: IPacket

The header, contain all important information from the packet, to specify the packet type as channel does and/or can has the data, which that are important to handle with

The encoding should be UTF-8

Specified by:

getHeader in interface IPacket

Returns:

the header as JsonDocument instance from this packet

getBody

public byte[] getBody()

Description copied from interface: IPacket

Returns the packet body, for transport for extra data, like files or zip archives or something else

The max length of the body can only be (Integer.MAX_VALUE - 1)

Specified by:

getBody in interface IPacket

Returns:

the body as byte array in bytes
