public class SerialPortEvent

extends EventObject

See Also:

SerialPort, SeriallPortEventListener, EventObject

BI

Break interrupt.

CD

Carrier detect.

CTS

Clear to send.

DATA_AVAILABLE

Data available at the serial port.

DSR

Data set ready.

eventType

The type of event. Deprecated.

FE

Framing error.

OE

Overrun error.

OUTPUT_BUFFER_EMPTY

Output buffer is empty.

PE

Parity error.

RI

Ring indicator.

SerialPortEvent(SerialPort, int, boolean, boolean)

Constructs a SerialPortEvent with the specified serial port, event type, old and new values.

getEventType()

Gets the type of this event.

getNewValue()

Gets the new value of the state change that caused the SerialPortEvent to be propagated.

getOldValue()

Gets the old value of the state change that caused the SerialPortEvent to be propagated.

 public int eventType

Note: eventType is deprecated. Replaced by getEventType method.

The type of event.

 public static final int DATA_AVAILABLE

Data available at the serial port. This event will be generated once when new data arrive at the serial port. Even if the user doesn't read the data, it won't be generated again until next time new data arrive.

 public static final int OUTPUT_BUFFER_EMPTY

Output buffer is empty. The event will be generated after a write is completed, when the system buffer becomes empty again.

 public static final int CTS

Clear to send.

 public static final int DSR

Data set ready.

 public static final int RI

Ring indicator.

 public static final int CD

Carrier detect.

 public static final int OE

Overrun error.

 public static final int PE

Parity error.

 public static final int FE

Framing error.

 public static final int BI

Break interrupt.

 public SerialPortEvent(SerialPort srcport,
                        int eventtype,
                        boolean oldvalue,
                        boolean newvalue)

Constructs a SerialPortEvent with the specified serial port, event type, old and new values. Application programs should not directly create SerialPortEvent objects.

Parameters:

srcport - source parallel port

eventtype - event type

oldvalue - old value

newvalue - new value

 public int getEventType()

Gets the type of this event.

Returns:

integer that can be equal to one of the following static variables: BI, CD, CTS, DATA_AVAILABLE, DSR, FE, OE, OUTPUT_BUFFER_EMPTY, PE or RI.

 public boolean getNewValue()

Gets the new value of the state change that caused the SerialPortEvent to be propagated. For example, when the CD bit changes, newValue reflects the new value of the CD bit.

 public boolean getOldValue()

Gets the old value of the state change that caused the SerialPortEvent to be propagated. For example, when the CD bit changes, oldValue reflects the old value of the CD bit.
