Package-level declarations

Types

abstract class AbstractDoubleExporter @JvmOverloads constructor(val precision: Int? = null) : Extractor<Double>

Double-formatting utility. Provided a precision representing the significant digits, formats doubles accordingly, using Locale.ENGLISH. If null is provided, returns the default conversion to string.

ExecutionTime

class ExecutionTime @JvmOverloads constructor(val precision: Int? = null) : AbstractDoubleExporter

An extractor which provides informations about the running time of the simulation. Optionally, a precision (significant digits) can be provided.

MeanSquaredError

class MeanSquaredError<T> @JvmOverloads constructor(incarnation: Incarnation<T, *>, localCorrectValueMolecule: String, localCorrectValueProperty: String = "", statistics: String, localValueMolecule: String, localValueProperty: String = "", val precision: Int? = null) : AbstractDoubleExporter

Exports the Mean Squared Error for the concentration of some molecule, given another molecule that carries the correct result. The correct value is extracted from every node, then the provided {@link UnivariateStatistic} is applied to get a single, global correct value. Then, the actual value is extracted from every node, its value is compared (subtracted) to the computed correct value, it gets squared, and then logged.

MoleculeReader

class MoleculeReader @JvmOverloads constructor(moleculeName: String, property: String?, incarnation: Incarnation<*, *>, filter: ExportFilter, aggregatorNames: List<String>, val precision: Int? = null) : AbstractDoubleExporter

Reads the value of a molecule and logs it.

NodesPositions

class NodesPositions<T, P : Position<P>>(environment: Environment<T, P>) : AbstractDoubleExporter

Exports the positions of all nodes in the environment. The output is a table where, for each node, there is a column per dimension.

NumberOfNodes

class NumberOfNodes : Extractor<Int>

Logs the number of nodes in the scenario.

Time

class Time @JvmOverloads constructor(val precision: Int? = null) : AbstractDoubleExporter

Exports a column with the current time.
