    nz.org.riskscape.problem.ResultOrProblems<nz.org.riskscape.engine.rl.RealizedExpression>
    realizeConstant(nz.org.riskscape.rl.ast.Expression expression)
    Attempts to realize the given expression against an empty struct, returning a meaningful problem if it looks like it failed to realize because it had property access problems (meaning it wasn't constant as it relies on the input scope)

    • realizeConstant

      public nz.org.riskscape.problem.ResultOrProblems<nz.org.riskscape.engine.rl.RealizedExpression> realizeConstant(nz.org.riskscape.rl.ast.Expression expression)

      Attempts to realize the given expression against an empty struct, returning a meaningful problem if it looks like it failed to realize because it had property access problems (meaning it wasn't constant as it relies on the input scope)

      Specified by:
      realizeConstant in interface nz.org.riskscape.engine.rl.ExpressionRealizer
      Returns:
      a RealizedExpression that is constant, i.e should succeed when called like expr.evaluate(Tuple.EMPTY_TUPLE) and should always return the same result.
