boolean send(java.nio.ByteBuffer buffer)
             throws java.io.IOException

Send a complete message.

Parameters:

buffer - the message to send

Returns:

the result of the send operation; true if the message was sent, or false if it would block

           int offs,
           int len)
             throws java.io.IOException

Send a complete message.

Parameters:

buffers - the buffers holding the message to send

offs - the offset into the buffer array of the first buffer

len - the number of buffers that contain data to send

Returns:

the result of the send operation; true if the message was sent, or false if it would block
