Method Detail

getBuffer

public ByteBuf getBuffer(int size)

Description copied from interface: BufferProvider

Gets a buffer with the givens capacity.

Specified by:

getBuffer in interface BufferProvider

Parameters:

size - the size required for the buffer

Returns:

a ByteBuf with the given size, which is now owned by the caller and must be released.

open

public void open()
          throws IOException

Description copied from interface: Stream

Open the stream.

Specified by:

open in interface Stream

Throws:

IOException - if an I/O error occurs

openAsync

public void openAsync(AsyncCompletionHandler<Void> handler)

Description copied from interface: Stream

Open the stream asynchronously.

Specified by:

openAsync in interface Stream

Parameters:

handler - the completion handler for opening the stream

write

public void write(List<ByteBuf> buffers)
           throws IOException

Description copied from interface: Stream

Write each buffer in the list to the stream in order, blocking until all are completely written.

Specified by:

write in interface Stream

Parameters:

buffers - the buffers to write

Throws:

IOException - if there are problems writing to the stream

read

public ByteBuf read(int numBytes)
             throws IOException

Description copied from interface: Stream

Read from the stream, blocking until the requested number of bytes have been read.

Specified by:

read in interface Stream

Parameters:

numBytes - The number of bytes to read into the returned byte buffer

Returns:

a byte buffer filled with number of bytes requested

Throws:

IOException - if there are problems reading from the stream

writeAsync

public void writeAsync(List<ByteBuf> buffers,
                       AsyncCompletionHandler<Void> handler)

Description copied from interface: Stream

Write each buffer in the list to the stream in order, asynchronously. This method should return immediately, and invoke the given callback on completion.

Specified by:

writeAsync in interface Stream

Parameters:

buffers - the buffers to write

handler - invoked when the read operation has completed

readAsync

public void readAsync(int numBytes,
                      AsyncCompletionHandler<ByteBuf> handler)

Description copied from interface: Stream

Read from the stream, asynchronously. This method should return immediately, and invoke the given callback when the number of requested bytes have been read.

Specified by:

readAsync in interface Stream

Parameters:

numBytes - the number of bytes

handler - invoked when the read operation has completed

getAddress

public ServerAddress getAddress()

Description copied from interface: Stream

The address that this stream is connected to.

Specified by:

getAddress in interface Stream

Returns:

the address

close

public void close()

Closes the connection.

Specified by:

close in interface Stream

isClosed

public boolean isClosed()

Description copied from interface: Stream

Returns the closed state of the connection

Specified by:

isClosed in interface Stream

Returns:

true if connection is closed

getServerAddress

public ServerAddress getServerAddress()

getSettings

public SocketSettings getSettings()

getGroup

public AsynchronousChannelGroup getGroup()
