Class CountingEvent

java.lang.Object

com.oracle.deviceaccess.PeripheralEvent<PulseCounter>

com.oracle.deviceaccess.counter.CountingEvent

public class CountingEvent
extends PeripheralEvent<PulseCounter>

The CountingEvent class encapsulates pulse counting conditions such as counter terminal value reached or counting session time interval expired.
When/if counting events for the same pulse counter are coalesced the count value and the type (terminal value reached or time interval expired) retained are that of the last occurrence.

CountingEvent

public CountingEvent(PulseCounter counter,
             int type,
             int value,
             long interval)

Creates a new CountingEvent with the specified type, pulse count value and actual counting time interval and time-stamped with the current time.

Parameters:

counter - the source pulse counter.

type - the type of counting condition being notified: INTERVAL_EXPIRED or TERMINAL_VALUE_REACHED.

value - the pulse count value.

interval - the actual counting time interval (in microseconds).

Throws:

java.lang.NullPointerException - if counter is null.

java.lang.IllegalArgumentException - if type is not one of the defined types or if value or interval is negative.

CountingEvent

public CountingEvent(PulseCounter counter,
             int type,
             int value,
             long interval,
             long timeStamp,
             int timeStampMicros)

Creates a new CountingEvent with the specified type, pulse count value, actual counting time interval and timestamp.

Parameters:

counter - the source pulse counter.

type - the type of counting condition being notified: INTERVAL_EXPIRED or TERMINAL_VALUE_REACHED.

value - the pulse count value.

interval - the actual counting time interval (in microseconds).

timeStamp - the timestamp (in milliseconds).

timeStampMicros - the additional microseconds to the timestamp.

Throws:

java.lang.NullPointerException - if counter is null.

java.lang.IllegalArgumentException - if type is not one of the defined types or if value, interval, timeStamp or timeStampMicros is negative.

Method Detail

getInterval

public long getInterval()

Returns the actual counting time interval (in microseconds). The actual counting time interval may be smaller than the defined counting time interval if the count terminal value has been reached.

Returns:

the actual counting time interval.

getType

public int getType()

Returns the type of counting condition being notified.

Returns:

the type of counting condition being notified: INTERVAL_EXPIRED or TERMINAL_VALUE_REACHED..

getValue

public int getValue()

Returns the pulse count value.

Returns:

the pulse count value.
