reset

public void reset()

Reset the counter in a non atomic fashion, at a quiscient state this method will reset the counter to its initial value, but in a concurrent state, interleaving operations affect is not deterministic and may be overridden or accumulated. A normal use would be a reset of statistic counter that the precise accumulation of statistics is not mandatory.
