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

getAccumulatedTimeMillis

public long getAccumulatedTimeMillis()

Description copied from interface: AccumulatedTimerSupplier

The accumulated time so far. For aggregations, this is the sum over all partitions of the to be the sum over all partitions of the partition's AccumulatedTimerSupplier.getAccumulatedTimeMillis(). This value is undefined if the timer is StatisticState.UNAVAILABLE.

Specified by:

getAccumulatedTimeMillis in interface AccumulatedTimerSupplier
