types of an OCL expression in ETL [message #1751684]

I know ATL does not offer any support nor API to statically obtain the types of an OCL expression. I want to know does ETL offer? (the model with the OCL navigations parsed)

Hi,

anATLyzer [1] may be providing such capabilities for ATL. For ETL, Haetae could be of use [2] but I'm afraid I don't have much hands-on experience with it. The fastest way to contact Haetae's developers would be to open an issue on GitHub.

Cheers,
Dimitris

Hi there,

To obtain the types of expression of an ETL transformation, in Eclipse, Haetae provides an "overview" view to view the entire tree of the program. However, Haetae provides a "best guess" solution. Expressions with type "Any" will be recorded as "Any" on the overview, although internally different things happen.

You can also do this programmatically, but that requires further explanation. Please let me know if this is the direction you want to go.

Cheers,
Will

thank you.

I need the extraction of the navigation paths, traversing through iterators, ...
e.g. if we have "s.ownedProperty.class -> collect(e|e.attribute.type) -> collect(f|f.date)", where "s" is of type "Bank". I want to retrieve : "Bank.ownedProperty.class.attribute.type.date"

Does Haetae provide this facility or I should write the code myself?

Hi,

In theory, in EOL you can write something like s.ownedProperty.class.attribute.type.date, depending on the types of the properties you are accessing here (which I do not know).

Haetae does not provide facility for refactoring as it is non-invasive to EOL programs (at least for now).

Cheers,
Will
