Notes on Table 1
- In RBD a DataItem can only be used for primitive types. In EDT it can be used for any type.
- See also Table 2: Function Parameters.
- Interfaces can be implemented by services and handlers (every kind of "logic part" which can be instantiated).
- There are no called programs in EDT. Use libraries for "local calls" and services for "remote calls".
- We intend to support function overloading in all implementations, even JavaScript.
- Nullability means that a variable may really be null. It's not an "I'm null" flag like in RBD. A NullValueException will be thrown if you try to access a field or function of a null variable, even a record. A NullValueException will be thrown if a null variable is an operand to a math operator, an array access, a substring access, a comparison, or a bitwise operator. The string concatenation operators will work the same as in RBD with respect to nulls. :: treats null as the empty string, and ?: results in null if either operand is null. A question mark won't be allowed on the second operand of the AS and ISA operators (the name of the type).
