NodesPositions

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

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

Note: this exporter is not designed to handle changes in the environment topology like node removal or addition.

Functions

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

Extracts properties from an environment. The returned map must either:

Link copied to clipboard
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. Captures E to String conversions. The default implementation just runs a toString() conversion ver extractData's return value's values.
