RFC
- Packet
opcode=7: SERV gives CLIENT1 information about CLIENT2
+--------+------+---------+---------+
| opcode | port | IP size | address |
+--------+------+---------+---------+
| 7 | int | int | bytes |
+--------+------+---------+---------+- We don't need to know if the client exists or not (client's responsability).
- An IP Address is encoded as a sequence of bytes. It will always be preceded by the size of the address, coded in an int.
IPv4 = 32 bits = 4 bytesIPv6 = 128 bits = 16 bytes
Client.java
processInput():- Now parses commands (
argsstyle), to make theswitchcode easier for commands with arguments. - Is now safer to use for developpers : all cases end with
break, forget about thereturnthing.
- Now parses commands (
- Renamed
/wcommand to/private. Because/wwill be used later for private messages.- Syntax :
/private nicknamerequests a private communication tonickname. - Client is now able to write packets
opcode=6to the server. - Client is now able to read packets
opcode=7from the server.
- Syntax :
- Added method
packetClientInfoRequest(). - Added method
receiveClientInfoReply(). Added methodreadAddress(). - Progress :

9 receivePrivateComReply() todo
Context.java
- Added packet
opcode=6to the supported received packets. (+ CommandReader.java) - Added method
receivedClientInfoRequest(): server retrieves the destination nickname, gets the destination'sContext, then gets the port and IP from thatContext, and build the reply to the client.
Server.java
- Added method
getContextByNickname().
ClientGUI.java
- New class for a simple graphical user interface.
- ClientGUI will now retrieve user inputs, and give them to Client with this method. As ClientGUI is event based, the
while (!hasQuit && scanner.hasNextLine())is no longer needed.
Client.java
- Added
ClientGUIas a private field. - Anytime you want to use
System.out.println()for the chat, now useClientGUI.println()instead. Easy. getInput()method was removed.processInput()was added. It is called by ClientGUI when an user input event was triggered.- leaved -> left
Client.java
- Charsets, which are defined in the RFC, have been encapsulated.
- Casts in readByte conditions were removed, == supports bytes.
- Added enum OpCode and a readOpCode method to decrease confusion given the huge number of incoming different readBytes calls.
- Added a logger.
- Code fully documented.
Context.java
- refuseConnection now takes an error code as a parameter (cf RFC).
- Now refuses connection to clients with nicknames that are too long.
