Method Detail

getPlayerHook

public PacketFilterManager.PlayerInjectHooks getPlayerHook()

Retrieves how the server packets are read.

Returns:

Injection method for reading server packets.

getPlayerHook

public PacketFilterManager.PlayerInjectHooks getPlayerHook(GamePhase phase)

Retrieves how the server packets are read.

Parameters:

phase - - the current game phase.

Returns:

Injection method for reading server packets.

setPlayerHook

public void setPlayerHook(PacketFilterManager.PlayerInjectHooks playerHook)

Sets how the server packets are read.

Parameters:

playerHook - - the new injection method for reading server packets.

setPlayerHook

public void setPlayerHook(GamePhase phase,
                 PacketFilterManager.PlayerInjectHooks playerHook)

Sets how the server packets are read.

Parameters:

phase - - the current game phase.

playerHook - - the new injection method for reading server packets.

addPacketHandler

public void addPacketHandler(int packetID)

Add an underlying packet handler of the given ID.

Parameters:

packetID - - packet ID to register.

removePacketHandler

public void removePacketHandler(int packetID)

Remove an underlying packet handler of ths ID.

Parameters:

packetID - - packet ID to unregister.

getPlayerByConnection

public org.bukkit.entity.Player getPlayerByConnection(java.io.DataInputStream inputStream)

Retrieve a player by its DataInput connection.

Parameters:

inputStream - - the associated DataInput connection.

Returns:

The player.

injectPlayer

public void injectPlayer(org.bukkit.entity.Player player)

Initialize a player hook, allowing us to read server packets.

This call will be ignored if there's no listener that can receive the given events.

Parameters:

player - - player to hook.

isInjectionNecessary

public boolean isInjectionNecessary(GamePhase phase)

Determine if it's truly necessary to perform the given player injection.

Parameters:

phase - - current game phase.

Returns:

TRUE if we should perform the injection, FALSE otherwise.

handleDisconnect

public void handleDisconnect(org.bukkit.entity.Player player)

Invoke special routines for handling disconnect before a player is uninjected.

Parameters:

player - - player to process.

uninjectPlayer

public boolean uninjectPlayer(org.bukkit.entity.Player player)

Unregisters the given player.

Parameters:

player - - player to unregister.

Returns:

TRUE if a player has been uninjected, FALSE otherwise.

uninjectPlayer

public boolean uninjectPlayer(org.bukkit.entity.Player player,
                     boolean removeAuxiliary)

Unregisters the given player.

Parameters:

player - - player to unregister.

removeAuxiliary - - TRUE to remove auxiliary information, such as input stream and address.

Returns:

TRUE if a player has been uninjected, FALSE otherwise.

uninjectPlayer

public boolean uninjectPlayer(java.net.InetSocketAddress address)

Unregisters a player by the given address.

If the server handler has been created before we've gotten a chance to unject the player, the method will try a workaround to remove the injected hook in the NetServerHandler.

Parameters:

address - - address of the player to unregister.

serverHandler - - whether or not the net server handler has already been created.

Returns:

TRUE if a player has been uninjected, FALSE otherwise.

sendServerPacket

public void sendServerPacket(org.bukkit.entity.Player reciever,
                    PacketContainer packet,
                    boolean filters)
                      throws java.lang.reflect.InvocationTargetException

Send the given packet to the given reciever.

Parameters:

reciever - - the player receiver.

packet - - the packet to send.

filters - - whether or not to invoke the packet filters.

Throws:

java.lang.reflect.InvocationTargetException - If an error occured during sending.

processPacket

public void processPacket(org.bukkit.entity.Player player,
                 net.minecraft.server.Packet mcPacket)

Parameters:

player - - the sender.

mcPacket - - the packet to process.

Throws:

java.lang.IllegalAccessException - If the reflection machinery failed.

java.lang.reflect.InvocationTargetException - If the underlying method caused an error.

checkListener

Determine if the given listeners are valid.

Parameters:

listeners - - listeners to check.

checkListener

public void checkListener(PacketListener listener)

Determine if a listener is valid or not.

If not, a warning will be printed to the console.

Parameters:

listener - - listener to check.

getSendingFilters

Retrieve the current list of registered sending listeners.

Returns:

List of the sending listeners's packet IDs.

close

public void close()

scheduleDataInputRefresh
