1 The constant expression restrictions can be summarized as follows Constant expressions a can use primitive types and String only b allow primaries that are literals apart from null and constant variables only c allow constant expressions possibly parenthesised as subexpressions d allow operators except for assignment operators or instanceof and e allow type Creating a truly compile time generated constant dictionary in C is not really a straightforward task Actually none of the answers here really achieve that There is one solution though which meets your requirements although not necessarily a nice one remember that according to the C specification switch case tables are compiled to constant hash jump tables
There s How do I assign a constant value to a column as well as My attempt to do this doesn t work in X way why is it behaving unexpectedly I believe I ve addressed both points the first by referring to another answer Please read all of the text in my answer You are correct Default parameter for value must be a compile time constant Dynamically calculated value is not accepted by compiler against optional parameter The reason behind this may be that it is not definite that the dynamic value you

Lit is an important Spark function that you will use frequently but not for adding constant columns to DataFrames You ll commonly be using lit to create org apache spark sql Column objects because that s the column type required by most of the org apache spark sql functions Constant represents a static member whose value can never change This means that a constant value is defined in compile time With the statement public const TimeSpan theTime new TimeSpan 13 0 0 Are violated two axioms of constant fields Only the C built in types excluding System Object may be declared as const
