                     boolean nio)

receive

public void receive(Address sender,
                    ByteBuffer buf)

Description copied from class: ReceiverAdapter

The default implementation assumes that Buffer.flip() or Buffer.rewind() was called on buf before invoking this callback

Specified by:

receive in interface Receiver

Overrides:

receive in class ReceiverAdapter

Parameters:

sender - The sender of the message

buf - The buffer. An application typically de-serializes data from the buffer into objects used by the application. Note that when receive() returns, it is not safe to use the buffer any longer; if an application needs to use a buffer after this callback returns, it must make a copy.

Note that buf could be a direct ByteBuffer.

receive

public void receive(Address sender,
                    byte[] buf,
                    int offset,
                    int length)

Description copied from interface: Receiver

Delivers a message from a given sender to the application

Specified by:

receive in interface Receiver

Overrides:

receive in class ReceiverAdapter

Parameters:

sender - The sender of the message

buf - The buffer. An application typically de-serializes data from the buffer into objects used by the application. Note that when receive() returns, it is not safe to use the buffer any longer; if an application needs to use a buffer after this callback returns, it must make a copy.

offset - The offset at which the received data starts

length - The length of the received data

main

public static void main(String[] args)
                 throws Exception

Throws:

Exception
