1 year ago At present, a data pool item can be of either primitive or array-like type. In both cases, a data item has a single identifier. While specifying service 20, I realized that I need to be able to address individual elements of an array. I therefore need to extend the concept of "data item identifier" as follows:
- An array-like data pool item has an identifier for the entire data pool item and it has identifiers for each of its element
- If array-like data item A has N elements and the identifier for A is ID_A, then the identifiers for its elements are: ID_A+1, ... ID_A+N
This concept has, I believe, no impact on the validation tests of the existing services but it requires a change to the code generators because we need to generate the identifiers for the array elements
The concept of "multiplicity" for data pool items does not exist at specification level. I need to define it in the UM and in particular I need to define how identifiers are allocated to the elements of an array-like data item.
