Method Summary

Modifier and Type	Method and Description
void	receive(A sender, byte[] buf, int offset, int length) Delivers a message from a given sender to the application
void	receive(A sender, java.nio.ByteBuffer buf) Delivers a message from a given sender to the application

Method Detail

receive

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

Delivers a message from a given sender to the application

Parameters:

sender - The sender of the message

buf - The buffer. Invokers of receive() must ensure that the contents of buf are not overwritten, e.g. by copying it if a buffer is reused. The application can therefore hang on to buf as long as it needs to. When buf is not referenced any longer, it can get garbage collected.

offset - The offset at which the received data starts

length - The length of the received data

receive

void receive(A sender,
             java.nio.ByteBuffer buf)

Delivers a message from a given sender to the application

Parameters:

sender - The sender of the message

buf - The buffer. Invokers of receive() must ensure that the contents of buf are not overwritten, e.g. by copying it if a buffer is reused. The application can therefore hang on to buf as long as it needs to. When buf is not referenced any longer, it can get garbage collected.

Note that buf could be a direct ByteBuffer.
