Interface AsyncReadCallbackHandler

public interface AsyncReadCallbackHandler

Callback handler interface, used by AsyncQueueReader to notify custom code either about completion of specific ByteBuffer reading or about IO problem, which occured when reading data to a ByteBuffer

Method Summary

void	onException(Exception exception, SelectionKey key, ByteBuffer buffer, Queue<AsyncQueueReadUnit> remainingQueue) Method will be called by AsyncQueueReader, if error occured when reading from the SelectableChannel, which is associated with SelectionKey
void	onReadCompleted(SelectionKey key, SocketAddress srcAddress, AsyncQueueReadUnit readRecord) Method will be called by AsyncQueueReader, if data was read to the ByteBuffer from the SelectableChannel, associated with SelectionKey, and read data confirms to the user-specific condition (if any was set).

Method Detail

onReadCompleted

void onReadCompleted(SelectionKey key,
                     SocketAddress srcAddress,
                     AsyncQueueReadUnit readRecord)

Method will be called by AsyncQueueReader, if data was read to the ByteBuffer from the SelectableChannel, associated with SelectionKey, and read data confirms to the user-specific condition (if any was set).

Parameters:

key - SelectionKey, associated with input SelectableChannel

srcAddress - sender's SocketAddress

readRecord - AsyncWriteQueueRecord, which was successfuly read

onException

void onException(Exception exception,
                 SelectionKey key,
                 ByteBuffer buffer,
                 Queue<AsyncQueueReadUnit> remainingQueue)

Method will be called by AsyncQueueReader, if error occured when reading from the SelectableChannel, which is associated with SelectionKey

Parameters:

exception - occurred Exception

key - SelectionKey, associated with input SelectableChannel

buffer - ByteBuffer, which supposed to be used for asynchronous reading. ByteBuffer could contain some data, which was successfully read before error occured
