The Ast representation of the different aggregation functions

Variants

Count

Aggregation function to count the number of updated values on the accessed stream

Min

Aggregation function to return the minimum

Max

Aggregation function to return the minimum

Sum

Aggregation function to return the addition

Product

Aggregation function to return the product

Average

Aggregation function to return the average

Integral

Aggregation function to return the integral

Conjunction

Aggregation function to return the conjunction, i.e., the sliding window returns true iff ALL values on the accessed stream inside a window are assigned to true

Disjunction

Aggregation function to return the disjunction, i.e., the sliding window returns true iff AT LEAst ONE value on the accessed stream inside a window is assigned to true

Last

Aggregation function to return the last value, a time bounded hold

Variance

Aggregation function to return the variance of all values, assumes equal probability.

Covariance

Aggregation function to return the covariance of all values in a tuple stream, assumes equal probability.

StandardDeviation

Aggregation function to return the standard deviation of all values, assumes equal probability.

NthPercentile(u8)

Aggregation function to return the Nth-Percentile

Tuple Fields of NthPercentile

0: u8
