AbstractAggregatingDoubleExtractor

abstract class AbstractAggregatingDoubleExtractor @JvmOverloads constructor(filter: ExportFilter = CommonFilters.NOFILTER.filteringPolicy, aggregatorNames: List<String>, precision: Int? = null) : AbstractDoubleExtractor(source)

Aggregation of data extracted from the environment. The data is filtered and then aggregated using the provided aggregators. Provided a filter and a list of aggregatorNames and a precision, extracts data from the environment, filters it, and then aggregates it. Available aggregators can be found at this site.

Functions

extractData

override fun <T> extractData(environment: Environment<T, *>, reaction: Actionable<T>?, time: Time, step: Long): Map<String, Double>

Extracts properties from an environment.

extractDataAsText

override fun <T> extractDataAsText(environment: Environment<T, *>, reaction: Actionable<T>?, time: Time, step: Long): Map<String, String>

Same as extractData, but specifically meant for textual outputs.
