Notes on Table 1

  1. In RBD a DataItem can only be used for primitive types. In EDT it can be used for any type.
  2. See also Table 2: Function Parameters.
  3. Interfaces can be implemented by services and handlers (every kind of "logic part" which can be instantiated).
  4. There are no called programs in EDT. Use libraries for "local calls" and services for "remote calls".
  5. We intend to support function overloading in all implementations, even JavaScript.
  6. Records (including structured records) are value types, so record variables may be declared with a question mark following the name of the type to indicate that they're nullable. 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).
  7. The deployment descriptor will ONLY be used for deployment. Neither the Java or JavaScript generator will generate the deployment descriptor.
