DatagramChannelEndPoint

public DatagramChannelEndPoint(java.nio.channels.DatagramChannel channel,
                               ManagedSelector selector,
                               java.nio.channels.SelectionKey key,
                               Scheduler scheduler)

Method Detail

getChannel

public java.nio.channels.DatagramChannel getChannel()

Overrides:

getChannel in class SelectableChannelEndPoint

receive

public java.net.SocketAddress receive(java.nio.ByteBuffer buffer)
                               throws java.io.IOException

Receives data into the given buffer from the returned address.

This method should be used to receive UDP data.

Parameters:

buffer - the buffer to fill with data

Returns:

the peer address that sent the data

Throws:

java.io.IOException - if the receive fails

send

public boolean send(java.net.SocketAddress address,
                    java.nio.ByteBuffer... buffers)
             throws java.io.IOException

Sends to the given address the data in the given buffers.

This methods should be used to send UDP data.

Parameters:

address - the peer address to send data to

buffers - the buffers containing the data to send

Returns:

true if all the buffers have been consumed

Throws:

java.io.IOException - if the send fails

write(Callback, SocketAddress, ByteBuffer...)

write

public void write(Callback callback,
                  java.net.SocketAddress address,
                  java.nio.ByteBuffer... buffers)
           throws java.nio.channels.WritePendingException

Writes to the given address the data contained in the given buffers, and invokes the given callback when either all the data has been sent, or a failure occurs.

Parameters:

callback - the callback to notify of the success or failure of the write operation

address - the peer address to send data to

buffers - the buffers containing the data to send

Throws:

java.nio.channels.WritePendingException - if a previous write was initiated but was not yet completed
