Mean of the values within a moving window of the input. The denominator is the number of values (non-NaN entries) in the rolling buffer.
Value parameters
buf
Rolling buffer to keep track of the input for a given window.
minNumValues
Minimum number of values that must be present within the buffer for an average to be emitted. If there are not enough non-NaN values, then NaN will be emitted.
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.
