wrapChannel

public static AsyncTcpSocketImpl wrapChannel(Eventloop eventloop,
                                             SocketChannel socketChannel,
                                             SocketSettings socketSettings)

wrapChannel

public static AsyncTcpSocketImpl wrapChannel(Eventloop eventloop,
                                             SocketChannel socketChannel)

withInspector

public AsyncTcpSocketImpl withInspector(@Nullable
                                        AsyncTcpSocketImpl.Inspector inspector)

setEventHandler

public void setEventHandler(AsyncTcpSocket.EventHandler eventHandler)

Specified by:

setEventHandler in interface AsyncTcpSocket

getConnectionCount

public static int getConnectionCount()

register

public final void register()

read

public void read()

Description copied from interface: AsyncTcpSocket

Must be called to inform the async socket that additional read data is needed.

Unless called, the socket won't read any data from network and therefore won't invoke AsyncTcpSocket.EventHandler.onRead(ByteBuf) callback.

Each read invocation may result in at most one AsyncTcpSocket.EventHandler.onRead(ByteBuf) callbacks.

This operation is idempotent and may be called several times prior to actual onRead callbacks.

Specified by:

read in interface AsyncTcpSocket

onReadReady

public void onReadReady()

Specified by:

onReadReady in interface NioChannelEventHandler

write

public void write(ByteBuf buf)

Description copied from interface: AsyncTcpSocket

Asynchronously writes data to network.

When written data is flushed, AsyncTcpSocket.EventHandler.onWrite() method will be called

Specified by:

write in interface AsyncTcpSocket

Parameters:

buf - bytes of data

writeEndOfStream

public void writeEndOfStream()

Description copied from interface: AsyncTcpSocket

Informs socket that no more data will be written. Any pending write data is expected to be delivered with corresponding AsyncTcpSocket.EventHandler.onWrite() confirmation. This operation is idempotent. No subsequent AsyncTcpSocket.EventHandler.onWrite() operations on the socket must be called afterwards.

Specified by:

writeEndOfStream in interface AsyncTcpSocket

onWriteReady

public void onWriteReady()

Specified by:

onWriteReady in interface NioChannelEventHandler

close

public void close()

Description copied from interface: AsyncTcpSocket

Closes socket, regardless of any remaining buffered data. This operation is idempotent. No subsequent operations on the socket must be called afterwards.

After calling this method no more event handler methods will be invoked

Specified by:

close in interface AsyncTcpSocket

isOpen

public boolean isOpen()

getRemoteSocketAddress

public InetSocketAddress getRemoteSocketAddress()

Specified by:

getRemoteSocketAddress in interface AsyncTcpSocket

getSocketChannel

public SocketChannel getSocketChannel()

toString

public String toString()

Overrides:

toString in class Object
