| DeleteHandler.java | Class | Handler for
Delete operations (which usually occur as parts of
Transaction requests).
When a
Delete operation is performed, the following actions are taken:
- the
FeatureId s of all (root) feature instances that match the associated
Filter are determined
- the
FeatureGraph is built in order to determine which features may be deleted
without removing subfeatures of independent features
- the
TableGraph is built that contains explicit information on all table rows that
have to be deleted (and their dependencies)
- the
TableNode s of the
TableGraph are sorted in topological order, i.e.
|
