getStreamReader

public StreamReader getStreamReader()

Description copied from interface: Connection

Get the Connection StreamReader, to read data from the Connection.

Returns:

getStreamWriter

public StreamWriter getStreamWriter()

Description copied from interface: Connection

Get the Connection StreamWriter, to write data to the Connection.

Returns:

preClose

protected void preClose()

Specified by:

preClose in class AbstractNIOConnection

getPeerAddress

public SocketAddress getPeerAddress()

Returns the address of the endpoint this Connection is connected to, or null if it is unconnected.

Returns:

the address of the endpoint this Connection is connected to, or null if it is unconnected.

getLocalAddress

public SocketAddress getLocalAddress()

Returns the local address of this Connection, or null if it is unconnected.

Returns:

setReadBufferSize

public void setReadBufferSize(int readBufferSize)

Description copied from interface: Connection

Set the default size of Buffers, which will be allocated for reading data from Connection.

Specified by:

setReadBufferSize in interface Connection<SocketAddress>

Overrides:

setReadBufferSize in class AbstractNIOConnection

Parameters:

readBufferSize - the default size of Buffers, which will be allocated for reading data from Connection.

setWriteBufferSize

public void setWriteBufferSize(int writeBufferSize)

Description copied from interface: Connection

Set the default size of Buffers, which will be allocated for writing data to Connection.

read

public Future<ReadResult<Buffer,SocketAddress>> read(Buffer buffer,
                                                     CompletionHandler<ReadResult<Buffer,SocketAddress>> completionHandler,

                                              throws IOException

Description copied from interface: Readable

Method reads data to the buffer.

Parameters:

buffer - the buffer, where data will be read

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

condition - Condition, which will be checked each time new portion of a data was read to a buffer. The condition can decide, whether asynchronous read is completed or not.

Returns:

Future, using which it's possible to check the result

Throws:

IOException

write

public Future<WriteResult<Buffer,SocketAddress>> write(SocketAddress dstAddress,
                                                       Buffer buffer,
                                                       CompletionHandler<WriteResult<Buffer,SocketAddress>> completionHandler)
                                                throws IOException

Description copied from interface: Writable

Method writes the buffer to the specific address.

Parameters:

dstAddress - the destination address the buffer will be sent to

buffer - the buffer, from which the data will be written

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

Returns:

Future, using which it's possible to check the result

Throws:

IOException
