  lejos.nxt.comm.NXTConnection
      lejos.nxt.comm.USBConnection

All Implemented Interfaces:

Connection, InputConnection, OutputConnection, StreamConnection

public class USBConnection
extends NXTConnection

Provides a USB connection Supports both packetized, raw and stream based communincation. Blocking and non-blocking I/O. Notes When using the low level read/write functions no buffering is provided. This means that for read operations te entire packet must be read or data will be lost. A USB packet has a max size of 64 bytes. The Stream based functions take care of this automatically. When operating in RAW mode low level USB packets may be read and written. however this mode has no concept of EOF or start of a connection. When using PACKET mode each packet has a single byte header added to it. This is used to provide a simple start of connection/EOF model.
