Struct Window

Source 
pub struct Window<Aggr: WindowAggregation> {
    pub target: StreamReference,
    pub caller: StreamReference,
    pub aggr: Aggr,
    /* private fields */
}
Expand description

Represents an instance of a sliding or a discrete window aggregation

The generatic Aggr defines if the instance is a slinding window or a discrete window. The field aggr contains the data that is specific for a discrete of sliding window. The other data is used for a discrete and a sliding window.

Fields§

§target: StreamReference

The stream whose values will be aggregated

§caller: StreamReference

The stream calling and evaluating this window

§aggr: Aggr

The data that differentiates a sliding and a discrete window

This field can either has the type SlidingAggr or DiscreteAggr.

Trait Implementations§

Source§

impl<A: WindowAggregation> Aggregation for Window<A>

Source§

fn reference(&self) -> WindowReference

Returns the reference of the window

Source§

fn id(&self) -> ExprId

Returns the Id of the expression in which this window is accessed

The return value contains the Id of the expression that uses the produced value. This value is NOT the id of the window.
