Constructor Detail

TinyProtocol1_7

public TinyProtocol1_7(org.bukkit.plugin.Plugin plugin)

Construct a new instance of TinyProtocol, and start intercepting packets for all connected clients and future clients.

You can construct multiple instances per plugin.

Parameters:

plugin - - the plugin.

Method Detail

onPacketOutAsync

public java.lang.Object onPacketOutAsync(org.bukkit.entity.Player receiver,
                                         java.lang.Object packet)

Invoked when the server is starting to send a packet to a player.

Note that this is not executed on the main thread.

Parameters:

receiver - - the receiving player, NULL for early login/status packets.

packet - - the packet being sent.

Returns:

The packet to send instead, or NULL to cancel the transmission.

onPacketInAsync

public java.lang.Object onPacketInAsync(org.bukkit.entity.Player sender,
                                        java.lang.Object packet)

Invoked when the server has received a packet from a given player.

Use Channel.remoteAddress() to get the remote address of the client.

Parameters:

sender - - the player that sent the packet, NULL for early login/status packets.

packet - - the packet being received.

Returns:

The packet to recieve instead, or NULL to cancel.

sendPacket

public void sendPacket(org.bukkit.entity.Player player,
                       java.lang.Object packet)

Send a packet to a particular player.

Note that onPacketOutAsync(Player, Object) will be invoked with this packet.

Specified by:

sendPacket in interface AbstractTinyProtocol

Parameters:

player - - the destination player.

packet - - the packet to send.

sendPacket

public void sendPacket(net.minecraft.util.io.netty.channel.Channel channel,
                       java.lang.Object packet)

Send a packet to a particular client.

Note that onPacketOutAsync(Player, Object) will be invoked with this packet.

Parameters:

channel - - client identified by a channel.

packet - - the packet to send.

receivePacket

public void receivePacket(org.bukkit.entity.Player player,
                          java.lang.Object packet)

Pretend that a given packet has been received from a player.

Note that onPacketInAsync(Player, Object) will be invoked with this packet.

Specified by:

receivePacket in interface AbstractTinyProtocol

Parameters:

player - - the player that sent the packet.

packet - - the packet that will be received by the server.

receivePacket

public void receivePacket(net.minecraft.util.io.netty.channel.Channel channel,
                          java.lang.Object packet)

Pretend that a given packet has been received from a given client.

Note that onPacketInAsync(Player, Object) will be invoked with this packet.

Parameters:

channel - - client identified by a channel.

packet - - the packet that will be received by the server.

getHandlerName

protected java.lang.String getHandlerName()

Retrieve the name of the channel injector, default implementation is "tiny-" + plugin name + "-" + a unique ID.

Note that this method will only be invoked once. It is no longer necessary to override this to support multiple instances.

Returns:

A unique channel handler name.

injectPlayer

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

Add a custom channel handler to the given player's channel pipeline, allowing us to intercept sent and received packets.

This will automatically be called when a player has logged in.

Specified by:

injectPlayer in interface AbstractTinyProtocol

Parameters:

player - - the player to inject.

injectChannel

public void injectChannel(net.minecraft.util.io.netty.channel.Channel channel)

Add a custom channel handler to the given channel.

Parameters:

channel - - the channel to inject.

getChannel

public net.minecraft.util.io.netty.channel.Channel getChannel(org.bukkit.entity.Player player)

Retrieve the Netty channel associated with a player. This is cached.

Parameters:

player - - the player.

Returns:

The Netty channel.

getProtocolVersion

public int getProtocolVersion(org.bukkit.entity.Player player)

Specified by:

getProtocolVersion in interface AbstractTinyProtocol

uninjectPlayer

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

Uninject a specific player.

Specified by:

uninjectPlayer in interface AbstractTinyProtocol

Parameters:

player - - the injected player.

uninjectChannel

public void uninjectChannel(net.minecraft.util.io.netty.channel.Channel channel)

Uninject a specific channel.

This will also disable the automatic channel injection that occurs when a player has properly logged in.

Parameters:

channel - - the injected channel.

hasInjected

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

Determine if the given player has been injected by TinyProtocol.

Specified by:

hasInjected in interface AbstractTinyProtocol

Parameters:

player - - the player.

Returns:

TRUE if it is, FALSE otherwise.

hasInjected

public boolean hasInjected(net.minecraft.util.io.netty.channel.Channel channel)

Determine if the given channel has been injected by TinyProtocol.

Parameters:

channel - - the channel.

Returns:

TRUE if it is, FALSE otherwise.

close

public final void close()

Cease listening for packets. This is called automatically when your plugin is disabled.

Specified by:

close in interface AbstractTinyProtocol
