Constructor Detail

UARTEvent

public UARTEvent(UART uart,
         int id)

Creates a new UARTEvent with the specified value and time-stamped with the current time.

Parameters:

uart - the source uart.

id - the event ID: INPUT_DATA_AVAILABLE, INPUT_BUFFER_OVERRUN or OUTPUT_BUFFER_EMPTY.

Throws:

java.lang.NullPointerException - if uart is null.

java.lang.IllegalArgumentException - if id is not a valid event ID.

UARTEvent

public UARTEvent(UART uart,
         int id,
         long timeStamp,
         int timeStampMicros)

Creates a new UARTEvent with the specified value and timestamp.

Parameters:

uart - the source uart.

id - the event ID: INPUT_DATA_AVAILABLE, INPUT_BUFFER_OVERRUN or OUTPUT_BUFFER_EMPTY.

timeStamp - the timestamp (in milliseconds).

timeStampMicros - the additional microseconds to the timestamp.

Throws:

java.lang.NullPointerException - if uart is null.

java.lang.IllegalArgumentException - if id is not a valid event ID or if timeStamp or timeStampMicros is negative.

Method Detail

getID

public int getID()

Returns this event ID.

Returns:

this event ID: INPUT_DATA_AVAILABLE, INPUT_BUFFER_OVERRUN or OUTPUT_BUFFER_EMPTY.
