Method Detail

write

public void write(Connection<SocketAddress> connection,
                  SocketAddress dstAddress,
                  WritableMessage message,
                  CompletionHandler<WriteResult<WritableMessage,SocketAddress>> completionHandler,
                  MessageCloner<WritableMessage> messageCloner)

Method writes the WritableMessage to the specific address.

Parameters:

connection - the Connection to write to

dstAddress - the destination address the WritableMessage will be sent to

message - the WritableMessage, from which the data will be written

completionHandler - CompletionHandler, which will get notified, when write will be completed

messageCloner - the MessageCloner, which will be able to clone the message in case it can't be completely written in the current thread.

write

@Deprecated
public void write(Connection<SocketAddress> connection,
                              SocketAddress dstAddress,

                              PushBackHandler pushBackHandler)

Deprecated.

Method writes the WritableMessage to the specific address.

Parameters:

connection - the Connection to write to

dstAddress - the destination address the WritableMessage will be sent to

message - the WritableMessage, from which the data will be written

completionHandler - CompletionHandler, which will get notified, when write will be completed

pushBackHandler - PushBackHandler, which will be notified if message was accepted by transport write queue or refused

write

public void write(Connection<SocketAddress> connection,
                  SocketAddress dstAddress,
                  WritableMessage message,
                  CompletionHandler<WriteResult<WritableMessage,SocketAddress>> completionHandler,
                  long timeout,
                  TimeUnit timeunit)

Method writes the WritableMessage to the specific address.

Parameters:

connection - the Connection to write to

dstAddress - the destination address the message will be sent to

message - the WritableMessage, from which the data will be written

completionHandler - CompletionHandler, which will get notified, when write will be completed

write

public void write(Connection<SocketAddress> connection,
                  SocketAddress dstAddress,
                  WritableMessage message,

                  long timeout,
                  TimeUnit timeunit)

Method writes the WritableMessage to the specific address.

Parameters:

connection - the Connection to write to

dstAddress - the destination address the message will be sent to

message - the WritableMessage, from which the data will be written

completionHandler - CompletionHandler, which will get notified, when write will be completed

write0

protected long write0(NIOConnection connection,
                      SocketAddress dstAddress,
                      WritableMessage message,
                      WriteResult<WritableMessage,SocketAddress> currentResult,
                      long timeout,
                      TimeUnit timeunit)
               throws IOException

Flush the buffer by looping until the Buffer is empty

Parameters:

connection - the Connection.

dstAddress - the destination address.

message -

currentResult - the result of the write operation

timeout - operation timeout value value

timeunit - the timeout unit

Returns:

The number of bytes written.

Throws:

IOException

getTransport

public TemporarySelectorsEnabledTransport getTransport()

writeNow0

protected abstract long writeNow0(NIOConnection connection,
                                  SocketAddress dstAddress,
                                  WritableMessage message,
                                  WriteResult<WritableMessage,SocketAddress> currentResult)
                           throws IOException

Throws:

IOException

canWrite

public boolean canWrite(Connection connection)

Return true if the connection has not exceeded it's maximum size in bytes of pending writes, otherwise false.

Parameters:

connection - the Connection to test whether or not the specified number of bytes can be written to.

Returns:

true if the connection has not exceeded it's maximum size in bytes of pending writes, otherwise false

notifyWritePossible

public void notifyWritePossible(Connection connection,
                                WriteHandler writeHandler)

Registers WriteHandler, which will be notified ones at least one byte can be written. This method call is equivalent to call notifyWritePossible(connection, writeHandler, 1); Note: using this method from different threads simultaneously may lead to quick situation changes, so at time WriteHandler is called - the queue may become busy again.

Parameters:

connection - Connection

writeHandler - WriteHandler to be notified.
