Offers expressions with operators like +, -, * and /.
An implementation of CompoundKey that operates on two operands which themselves can be CompoundKeys.
Example 1): For 'Customer', "SELECT FirstName+' '+LastName" (Operator plus, +).
Example 2): For 'Customer', 'SELECT DateOfBirth().Year-2021 AS Age. (Operator minus, -).
Example 3): For 'Orderline', 'SELECT Product.Name, Quantity, Product.UnitPrice, Product.UnitPrice*Quantity AS Sum' (Operator multiply / '*').
| FunctionKeys | All FunctionKeys chained at end of compound key (but before an eventual QuantileKey). |
| QuantileKey | Eventual final QuantileKey at end of compound key. |
| ToString | The ToString representation is the one relevant when used as key, like in IK or when selecting like 'SELECT {fieldName}'. |
| TryGetP | The outwards facing executor, understanding use of FunctionKeys. |
| TryGetPInternal | The internal executor, containing the specific functionality for how to evaluate the key. |
