Method Detail

open

void open()
   throws IOException

Open the stream.

Throws:

IOException - if an I/O error occurs

openAsync

void openAsync(AsyncCompletionHandler<Void> handler)

Open the stream asynchronously.

Parameters:

handler - the completion handler for opening the stream

write

void write(List<ByteBuf> buffers)
    throws IOException

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

Parameters:

buffers - the buffers to write

Throws:

IOException - if there are problems writing to the stream

read

ByteBuf read(int numBytes)
      throws IOException

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

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

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

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

Parameters:

buffers - the buffers to write

handler - invoked when the read operation has completed

readAsync

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

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

Parameters:

numBytes - the number of bytes

handler - invoked when the read operation has completed

getAddress

ServerAddress getAddress()

The address that this stream is connected to.

Returns:

the address

close

void close()

Closes the connection.

isClosed

boolean isClosed()

Returns the closed state of the connection

Returns:

true if connection is closed
