Class Cast

java.lang.Object
nz.org.riskscape.engine.function.BaseRealizableFunction
nz.org.riskscape.engine.function.lang.Cast
All Implemented Interfaces:
nz.org.riskscape.engine.rl.RealizableFunction
public class Cast extends BaseRealizableFunction

Function to allow users to cast attributes to the expected types.

Useful to apply wrapping types like within set/range to attributes from dynamic data sources.

Note: that function will blow up if the given value cannot be coerced to the required type.

      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
