Version:

1.1.0

Author:

Stanley Hillner

Field Summary

private DiffModel	diffModel The EMF-Model that contains the differences between both models.
private MapModel	mapModel The mapping created by the MappingBuilder.

Constructor Summary

protected

DiffBuilder(MapModel mapModel) Constructor for instantiating a new DiffBuilder with the mapping that is shall compute.

Method Summary

private void	attributeChanged(java.util.HashMap<java.lang.Integer,Group> groupObjects, MappingElement e) Method calculates if attributes of the elements have changed.
private void	elementMoved(java.util.HashMap<java.lang.Integer,Group> groupObjects, MappingElement e) Method detects changes of the element-positions.
private void	getAddRemoveElements(java.util.HashMap<java.lang.Integer,Group> groupObjects) Method calculates which elements were added to or removed from the original model.
private void	getChangedElements(java.util.HashMap<java.lang.Integer,Group> groupObjects) Method calculates which elements are contained in both models but have changed.
protected DiffModel	getDiff() Calculate the differences between both models.
private void	referenceChanged(java.util.HashMap<java.lang.Integer,Group> groupObjects, MappingElement e) Method calculates if references of the elements have changed.
