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

Formats the value using the given formatter. Read more
This method tests for self and other values to be equal, and is used by ==.
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
