write

public long write(java.nio.ByteBuffer[] buffers,
                  int array_offset,
                  int length)
           throws java.io.IOException

Description copied from interface: Transport

Write data to the transport from the given buffers. NOTE: Works like GatheringByteChannel.

Specified by:

write in interface Transport

Parameters:

buffers - from which bytes are to be retrieved

array_offset - offset within the buffer array of the first buffer from which bytes are to be retrieved

length - maximum number of buffers to be accessed

Returns:

number of bytes written

Throws:

java.io.IOException - on write error

read

public long read(java.nio.ByteBuffer[] buffers,
                 int array_offset,
                 int length)
