detect.changes

Description

List the changes happened in the "new" model, compared to the "old" model, as they are defined in the owner CompareModels task. This task binds the list of elements of the new model that were not mapped to any element from the old model (orphans) into the <new>.orphans project property. It binds the list of elements of the old model that were not mapped to any element from the first model (orphans) into <old>.orphans project property. Where <new> and <old> are the names of the new and old extents defined in the wrapping task. This task executes the nested tasks for each element from the new model that was mapped to element(s) from the old model and binds in:

<new>.element property the element form the new model;
<old>.element property the corresponding element form the old model;
attribute.names property the list of names of attributes detected as changed;
association.names property the list of names of associations detected as changed.
The current value of the association in the first model can be retrieved using <get path="<association name>" property="element"> task;
for each association name two additional properties are defined:
- <association name>.added contains all elements from the new model that were added, when upgrading from old to the new model, i.e. they have no correspondents as associated in the old model
- <association name>.deleted contains all elements from the old model that were deleted, when upgrading from old to the new model, i.e. they have no correspondents as associated in the new model

Implementation class

net.mdatools.modelant.core.task.comparison.DetectElementChanges

Parameters

Attribute	Description	Type
new	The prefix name <new> of the property <new>.element where to bind the element from that model before executing the nested tasks (if any). Default: NEW	String
old	The prefix name <old> of the property <old>.element where to bind the element from that model before executing the nested tasks (if any). Default: OLD	String

Nested elements

Element	Description
Any task	These are tasks to execute in a separate local environment for each pair of corresponding objects and identified changes.
