unsigned char |
readByte()Read a single byte. Throws: Exception |

int |
readBytes(unsigned char* buffer, int n)Read a given number of bytes into an array. Returns the number of bytes actually read Note this method will throw an IOException (e.g. EOFException) only if no bytes can be read from the underlying stream. Throws: Exception |

int |
readBytes(unsigned char* buffer, int n, int min)Read a given number of bytes into an array. Returns the number of bytes actually read This method will throw an IOException (e.g. EOFException) if fewer than "min" bytes were read from the underlying stream. Throws: Exception |

void |
checkMachine()Test whether the machine running this code stores variables in a way consistent with the assumptions made when writing this class. This particular class makes no assumptions, so this method does nothing. Throws: HardwareException |
