Method Details

newEventLoopGroup

public static io.netty.channel.EventLoopGroup newEventLoopGroup(int numThreads)

Returns a newly-created EventLoopGroup.

Parameters:

numThreads - the number of event loop threads

newEventLoopGroup

public static io.netty.channel.EventLoopGroup newEventLoopGroup(int numThreads,
 boolean useDaemonThreads)

Returns a newly-created EventLoopGroup.

Parameters:

numThreads - the number of event loop threads

useDaemonThreads - whether to create daemon threads or not

newEventLoopGroup

public static io.netty.channel.EventLoopGroup newEventLoopGroup(int numThreads,
 String threadNamePrefix)

Returns a newly-created EventLoopGroup.

Parameters:

numThreads - the number of event loop threads

threadNamePrefix - the prefix of thread names

newEventLoopGroup

public static io.netty.channel.EventLoopGroup newEventLoopGroup(int numThreads,
 String threadNamePrefix,
 boolean useDaemonThreads)

Returns a newly-created EventLoopGroup.

Parameters:

numThreads - the number of event loop threads

threadNamePrefix - the prefix of thread names

useDaemonThreads - whether to create daemon threads or not

newEventLoopGroup

public static io.netty.channel.EventLoopGroup newEventLoopGroup(int numThreads,
 ThreadFactory threadFactory)

Returns a newly-created EventLoopGroup.

Parameters:

numThreads - the number of event loop threads

threadFactory - the factory of event loop threads

warmUp

public static io.netty.channel.EventLoopGroup warmUp(io.netty.channel.EventLoopGroup eventLoopGroup)

Warms up all EventLoops in the given eventLoopGroup by making sure all event loop threads are active.

directEventLoop

public static io.netty.channel.EventLoop directEventLoop()

Returns a special EventLoop which executes submitted tasks in the caller thread. Note that this EventLoop will raise an UnsupportedOperationException for any operations related with EventLoop shutdown or Channel registration.

serverChannelType

@Deprecated
public static Class<? extends io.netty.channel.ServerChannel> serverChannelType(io.netty.channel.EventLoopGroup eventLoopGroup)

Deprecated.

Use TransportType.serverChannelType(EventLoopGroup).

Returns the ServerChannel class that is available for this eventLoopGroup, for use in configuring a custom Bootstrap.

socketChannelType

@Deprecated
public static Class<? extends io.netty.channel.socket.SocketChannel> socketChannelType(io.netty.channel.EventLoopGroup eventLoopGroup)

Deprecated.

Use TransportType.socketChannelType(EventLoopGroup).

Returns the available SocketChannel class for eventLoopGroup, for use in configuring a custom Bootstrap.

datagramChannelType

@Deprecated
public static Class<? extends io.netty.channel.socket.DatagramChannel> datagramChannelType(io.netty.channel.EventLoopGroup eventLoopGroup)

Deprecated.

Use TransportType.datagramChannelType(EventLoopGroup).

Returns the available DatagramChannel class for eventLoopGroup, for use in configuring a custom Bootstrap.
