Abstract methods

def isEmpty: Boolean

Returns true if the state is the same as if it had been reset. This means that the state does not need to be stored and can just be recreated if a new values shows up. When processing a stream this is needed to avoid a memory leak for state objects if there are some transient values associated with a group by. This check becomes the effective lifespan for the state if no data is received for a given interval.

def next(v: Double): Double

Apply the next value from the input and return the computed value.

Apply the next value from the input and return the computed value.

Attributes

def reset(): Unit

Reset the state of the algorithm.

Reset the state of the algorithm.
