This
section discusses three forms of AADL model manipulation:
- Recording of plug-in processing
results as AADL property values in the model being
processed; the declarative AADL model or the AADL instance model is not modified
other than by associating AADL property values to AADL model objects.
- Modification of the model
being processed or creation of a new model; a declarative
AADL model or an AADL instance model is manipulated directly and the
modifications will result in any listener of the model to be notified of the changes. Deep-
copy methods provide for cloning of models in order to support what-if processing
based on changed models.
- Modification of the model
through EMF generated edit commands; a declarative
AADL model or an AADL instance model is manipulated through undoable commands
and the command history support reversing the model changes. Model listeners are
notified of model changesas above. The command-based model modification
provides for a more incremental form of what-if processing of models.
