    • getImplicitName

      public static String getImplicitName(nz.org.riskscape.rl.ast.FunctionCall aggregateFunctionCall, Collection<String> used)

      Returns an identifier for use in an aggregate struct expression for the given aggregation function call, where the user hasn't specified one.

      Note this is a simpler routine than that adopted for scalar expressions ExpressionRealizer.getImplicitName(RealizationContext, RealizedExpression, Collection) as a RealizedAggregateExpression does not expose as much 'structure' via its API (compared to a RealizedExpression. Given how realization for aggregate expressions is currently implemented, it doesn't really matter in practice and decent names are given in most situations that agree with the names that scalar struct expressions would be given.
