ElementTreeBottomUp Class
Does a depth-first search on the tree defined by an element and its sub-models and children. Sub-models are visited before their modeled elements, and children are visited before their parents.
The following callbacks allow the subclass to exclude elements and sub-trees from the search:
- ElementTreeBottomUp.shouldExploreModel, ElementTreeBottomUp.shouldExploreChildren
- ElementTreeBottomUp.shouldVisitElement, ElementTreeBottomUp.shouldVisitModel
The ElementTreeBottomUp.visitElement and ElementTreeBottomUp.visitModel callbacks allow the subclass to process the elements and models that are encountered in the search.
