Persist and restore polymorphic classes
---------------------------------------
Key: ISIS-118
URL: https://issues.apache.org/jira/browse/ISIS-118
Project: Isis
Issue Type: Bug
Components: Runtimes: Dflt: Objectstores: SQL
Affects Versions: 0.1.2-incubating
Reporter: Kevin Meyer
Assignee: Kevin Meyer
Currently, the SQL OS does not persist properties of super-classes when a
polymorphic class is persisted. Additionally, abstract classes and interfaces
are treated the same as concrete classes.
There are two obvious options:
1) The persisted polymorphic class creates a row in an uber-table of
concatenated properties of all super-classes.
2) The persisted polymorphic class creates rows in each table that corresponds
to a super-class (the concrete sub-class is contained in multiple tables, 1 per
super-class).
