      public nz.org.riskscape.engine.function.RiskscapeFunction build(nz.org.riskscape.engine.rl.RealizationContext context, nz.org.riskscape.rl.ast.FunctionCall functionCall, List<nz.org.riskscape.engine.types.Type> givenTypes) throws nz.org.riskscape.problem.ProblemException
      Description copied from class: BaseRealizableFunction

      This method is internal to the sub-class. Simple realizable functions can just implement this, to jump straight to the meat of building the realized function. You should throw a ProblemException for any errors encountered.

      Overrides:
      build in class BaseRealizableFunction
      Throws:
      nz.org.riskscape.problem.ProblemException
