All Implemented Interfaces:

public class MapList extends BaseRealizableFunction

Riskscape implementation of a list mapping function. Takes a list and a lambda function, returns a new list. Or, if the given arg is not a list, it applies the lambda expression to the arg directly. This allows a mapping expression to be applied to scalar values to make pipeline fragments easier to re-use, i.e. the same function applying expression can work on a list of hazard values or a single hazard value

      Description copied from class: BaseRealizableFunction

      Implements some basic boilerplate error checks by default. This allows simple realizable functions to just define the BaseRealizableFunction.build(RealizationContext, FunctionCall, List) guts of the function. More complicated realizable functions (i.e. with non-trivial type handling) may want to override this completely.
