UNAVAILABLE

public static final IntervalTimerSnapshot UNAVAILABLE

Constant that corresponds to a snapshot of a counter in the StatisticState.UNAVAILABLE state.

Constructor Details

IntervalTimerSnapshot

public IntervalTimerSnapshot(IntervalTimerSupplier source)

Create a snapshot of the given timer.

Parameters:

source - the timer

IntervalTimerSnapshot

public IntervalTimerSnapshot(StatisticState state,
 long startTimeMillis,
 long endTimeMillis)

Create a snapshot with the specified values

Parameters:

state - the state of the timer

startTimeMillis - the start time of the timer

endTimeMillis - the end time of the timer

Method Details

snapshot

public IntervalTimerSnapshot snapshot()

Description copied from interface: IntervalTimerSupplier

Creates a snapshot of this timer. If the timer is in the StatisticState.ACTIVE

Specified by:

snapshot in interface IntervalTimerSupplier

Specified by:

snapshot in interface StatisticSupplier

Returns:

a snapshot of this statistic.

getState

public StatisticState getState()

Description copied from interface: StatisticSupplier

Returns the current state of the supplier.

Specified by:

getState in interface StatisticSupplier

Returns:

the state of the supplier

getStartTimeMillis

public long getStartTimeMillis()

Description copied from interface: IntervalTimerSupplier

This will return the start time or an undefined value if never started.

Specified by:

getStartTimeMillis in interface IntervalTimerSupplier

Returns:

the start time or an undefined value if never started.

getEndTimeMillis

public long getEndTimeMillis()

Description copied from interface: IntervalTimerSupplier

Returns the end time if finished, the current time if running, or an undefined value if never started. If this timer corresponds to a snapshot of a timer that is in the StatisticState.ACTIVE state, then this value will reflect the time at which the snapshot was taken.

Specified by:

getEndTimeMillis in interface IntervalTimerSupplier

Returns:

the end time if finished, the current time if running, or an undefined value if never started

toString

public String toString()

Overrides:

toString in class Object
